SET SCHEMA checks. Any flavor of ALTER &lt;whatever&gt; .. SET SCHEMA fails if (1) the object is already in the new schema, (2) either the old or new schema is a temp schema, or (3) either the old or new schema is the TOAST schema. Extraced from a patch by Dimitri Fontaine, with additional hacking by me. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=44475e782f4674d257b9e5c1a3930218a4b4deea">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=44475e782f4674d257b9e5c1a3930218a4b4deea</a></li> <li>Remove belt-and-suspenders guards against buffer pin leaks. Forcibly releasing all leftover buffer pins should be unnecessary now that we have a robust ResourceOwner mechanism, and it significantly increases the cost of process shutdown. Instead, in an assert-enabled build, assert that no pins are held; in a non-assert-enabled build, do nothing. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c2281ac87cf4828b6b828dc8585a10aeb3a176e0">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c2281ac87cf4828b6b828dc8585a10aeb3a176e0</a></li> <li>Add inet_net_ntop.c to .gitignore. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2d1e426650fc93e5dfdd0178023485d38b03b102">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=2d1e426650fc93e5dfdd0178023485d38b03b102</a></li> <li>Object access hook framework, with post-creation hook. After a SQL object is created, we provide an opportunity for security or logging plugins to get control; for example, a security label provider could use this to assign an initial security label to newly created objects. The basic infrastructure is (hopefully) reusable for other types of events that might require similar treatment. KaiGai Kohei, with minor adjustments. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=cc1ed40d57aa68322e43a7b0a3320a6c5aff010a">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=cc1ed40d57aa68322e43a7b0a3320a6c5aff010a</a></li> <li>Add more ALTER &lt;object&gt; .. SET SCHEMA commands. This adds support for changing the schema of a conversion, operator, operator class, operator family, text search configuration, text search dictionary, text search parser, or text search template. Dimitri Fontaine, with assorted corrections and other kibitzing. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=55109313f96fb5c7d671fe8954b6f7fc0cca9631">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=55109313f96fb5c7d671fe8954b6f7fc0cca9631</a></li> <li>New contrib module, auth_delay. KaiGai Kohei, with a few changes by me. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fe7a32fc87e68edf014ee7e575f92cb027437ff4">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fe7a32fc87e68edf014ee7e575f92cb027437ff4</a></li> <li>Fix typo. Fujii Masao. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fab7fdb988f25438ded6c4a5c4b4f112f9decddb">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fab7fdb988f25438ded6c4a5c4b4f112f9decddb</a></li> </ul> <p>Peter Eisentraut a pouss&eacute;&nbsp;:</p> <ul> <li>Propagate ALTER TYPE operations to typed tables. This adds RESTRICT/CASCADE flags to ALTER TYPE ... ADD/DROP/ALTER/ RENAME ATTRIBUTE to control whether to alter typed tables as well. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f2a4278330ae12cd56b61c92a7debb9c9fca7b41">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=f2a4278330ae12cd56b61c92a7debb9c9fca7b41</a></li> <li>Remove useless whitespace at end of lines. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fc946c39aeacdff7df60c83fca6582985e8546c8">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=fc946c39aeacdff7df60c83fca6582985e8546c8</a></li> <li>Add index entries for more functions. Also, move index entries into the tables, closer to the function description, for easier editing in the future. Resort some tables to be more alphabetical. Remove the entries for count, max, min, and sum in the tutorial area, because that was felt to be confusing. Thom Brown. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4fc09ad00c3cc95003a5523d85999da1dd4f9d75">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4fc09ad00c3cc95003a5523d85999da1dd4f9d75</a></li> </ul> <p>Tom Lane a pouss&eacute;&nbsp;:</p> <ul> <li>Create the system catalog infrastructure needed for KNNGIST. This commit adds columns amoppurpose and amopsortfamily to pg_amop, and column amcanorderbyop to pg_am. For the moment all the entries in amcanorderbyop are "false", since the underlying support isn't there yet. Also, extend the CREATE OPERATOR CLASS/ALTER OPERATOR FAMILY commands with [ FOR SEARCH | FOR ORDER BY sort_operator_family ] clauses to allow the new columns of pg_amop to be populated, and create pg_dump support for dumping that information. I also added some documentation, although it's perhaps a bit premature given that the feature doesn't do anything useful yet. Teodor Sigaev, Robert Haas, Tom Lane. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=725d52d0c27cffe8c99bb78e2b0d2480d5cd702b">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=725d52d0c27cffe8c99bb78e2b0d2480d5cd702b</a></li> <li>Fix significant memory leak in contrib/xml2 functions. Most of the functions that execute XPath queries leaked the data structures created by libxml2. This memory would not be recovered until end of session, so it mounts up pretty quickly in any serious use of the feature. Per report from Pavel Stehule, though this isn't his patch. Back-patch to all supported branches. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4a2516a7f976e2f6671930904d4e97a4832eff9f">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=4a2516a7f976e2f6671930904d4e97a4832eff9f</a></li> <li>Remove bogus use of PGDLLIMPORT. That macro should be attached to extern declarations, not actual definitions of variables. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=1d9a0abec1224193fea3acf766b587fc3963a3b8">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=1d9a0abec1224193fea3acf766b587fc3963a3b8</a></li> <li>Fix portability issues in new src/port/inet_net_ntop.c file. 1. Don't #include postgres.h in a frontend build. 2. Don't assume that the backend's symbol PGSQL_AF_INET6 has anything to do with the constant that will be used by system library functions (because, in point of fact, it usually doesn't). Fortunately, PGSQL_AF_INET is equal to AF_INET, so we can just cater for both sets of values in one case construct without fear of conflict. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=3840bc0847aa1b635127ff4a55b5257c9ebc79b8">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=3840bc0847aa1b635127ff4a55b5257c9ebc79b8</a></li> <li>Clean up IPv4 vs IPv6 bogosity in connectFailureMessage(). Newly added code was supposing that "struct sockaddr_in" applies to IPv6. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=be3b666eb810089fd9a1d42e3888be52ab9ddb63">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=be3b666eb810089fd9a1d42e3888be52ab9ddb63</a></li> <li>Rewrite PQping to be more like what we agreed to last week. Basically, we want to distinguish all cases where the connection was not made from those where it was. A convenient proxy for this is to see if we got a message with a SQLSTATE code back from the postmaster. This presumes that the postmaster will always send us a SQLSTATE in a failure message, which is true for 7.4 and later postmasters in every case except fork failure. (We could possibly complicate the postmaster code to do something about that, but it seems not worth the trouble, especially since pg_ctl's response for that case should be to keep waiting anyway.) If we did get a SQLSTATE from the postmaster, there are basically only two cases, as per last week's discussion: ERRCODE_CANNOT_CONNECT_NOW and everything else. Any other error code implies that the postmaster is in principle willing to accept connections, it just didn't like or couldn't handle this particular request. We want to make a special case for ERRCODE_CANNOT_CONNECT_NOW so that "pg_ctl start -w" knows it should keep waiting. In passing, pick names for the enum constants that are a tad less likely to present collision hazards in future. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=db96e1ccfcb8f3514eef931bea9435974ec7ad28">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=db96e1ccfcb8f3514eef931bea9435974ec7ad28</a></li> <li>On further testing, PQping also needs an explicit check for AUTH_REQ. The pg_fe_sendauth code might fail if it can't handle the authentication request message type --- if so, ping should still say the server is up. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=49cd8a3f810467632260f16c7779f19212c1d094">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=49cd8a3f810467632260f16c7779f19212c1d094</a></li> <li>A bit more wordsmithing on the PQping documentation. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=d53c1255d9730b07d56166ace1191250ca76f496">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=d53c1255d9730b07d56166ace1191250ca76f496</a></li> <li>Point out in default_tablespace's description that CREATE DATABASE ignores it. Per gripe from Andreas Scherbaum. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c623365ff9a5ef937e05b85c2feb5a5c5cde9b3b">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c623365ff9a5ef937e05b85c2feb5a5c5cde9b3b</a></li> </ul> <p>Bruce Momjian a pouss&eacute;&nbsp;:</p> <ul> <li>When reporting the server as not responding, if the hostname was supplied, also print the IP address. This allows IPv4 and IPv6 failures to be distinguished. Also useful when a hostname resolves to multiple IP addresses. Also, remove use of inet_ntoa() and use our own inet_net_ntop() in all places, including in libpq, because it is thread-safe. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ba11258ccbf364d85de48b8b7fd46953ea7bb4f4">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=ba11258ccbf364d85de48b8b7fd46953ea7bb4f4</a></li> <li>Document that a CHECKPOINT before taking a file system snapshot can reduce recovery time. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7276ab5888d85782d988fc297ad2e176c7ad1bca">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=7276ab5888d85782d988fc297ad2e176c7ad1bca</a></li> <li>Properly add new inet_net_ntop file to libpq Makefile. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=58dfb07b5d84c0088033e2d22fc44df812fa6eb5">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=58dfb07b5d84c0088033e2d22fc44df812fa6eb5</a></li> <li>Restructure how libpq includes external C files, for clarity. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c6978ecd6f761388d8479c8b32cfd0dd2d2bd4ac">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c6978ecd6f761388d8479c8b32cfd0dd2d2bd4ac</a></li> <li>Fix getaddrinfo() in pgport to use proper parameters, as detected by Win32 buildfarm members. <a target="_blank" href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=212a1c7b0b4164e15381af327ee6656ae7e02298">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=212a1c7b0b4164e15381af327ee6656ae7e02298</a></li> <li>Add PQping and PQpingParams to libpq to allow detection of the server's status, including a status where the server is running but refuses a postgres connection.
