* Allow a user to kill his own queries using pg_cancel_backend()Magnus Hagander2012-01-15
| | | | | | | | | Allows a user to use pg_cancel_queries() to cancel queries in other backends if they are running under the same role. pg_terminate_backend() still requires superuser permissoins. Short patch, many authors working on the bikeshed: Magnus Hagander, Josh Kupershmidt, Edward Muller, Greg Smith.
* Make superuser imply replication privilege. The idea of a privilege thatHeikki Linnakangas2012-01-14
| | | | | | | | | | superuser doesn't have doesn't make much sense, as a superuser can do whatever he wants through other means, anyway. So instead of granting replication privilege to superusers in CREATE USER time by default, allow replication connection from superusers whether or not they have the replication privilege. Patch by Noah Misch, per discussion on bug report #6264
* Support CREATE TABLE (LIKE ...) with foreign tables and viewsPeter Eisentraut2012-01-10
| | | | | Composite types are not yet supported, because parserOpenTable() rejects them.
* Add compatibility note about grant options on GRANT reference pagePeter Eisentraut2012-01-09
| | | | | | | Point out in the compatibility section that granting grant options to PUBLIC is not supported by PostgreSQL. This is already mentioned earlier, but since it concerns the information schema, it might be worth pointing out explicitly as a compatibility issue.
* Rename the internal structures of the CREATE TABLE (LIKE ...) facilityPeter Eisentraut2012-01-07
| | | | | | | | | The original implementation of this interpreted it as a kind of "inheritance" facility and named all the internal structures accordingly. This turned out to be very confusing, because it has nothing to do with the INHERITS feature. So rename all the internal parser infrastructure, update the comments, adjust the error messages, and split up the regression tests.
* Fix typo, pg_types_date.h => pgtypes_date.h.Tom Lane2012-01-06
| | | | Spotted by Koizumi Satoru.
* Improve ALTER DOMAIN / DROP CONSTRAINT with nonexistent constraintPeter Eisentraut2012-01-05
| | | | | | | ALTER DOMAIN / DROP CONSTRAINT on a nonexistent constraint name did not report any error. Now it reports an error. The IF EXISTS option was added to get the usual behavior of ignoring nonexistent objects to drop.

* Rethink representation of index clauses' mapping to index columns.Tom Lane2011-12-24
| | | | | | | | | | | | | | | | | | | | | In commit e2c2c2e8b1df7dfdb01e7e6f6191a569ce3c3195 I made use of nested list structures to show which clauses went with which index columns, but on reflection that's a data structure that only an old-line Lisp hacker could love. Worse, it adds unnecessary complication to the many places that don't much care which clauses go with which index columns. Revert to the previous arrangement of flat lists of clauses, and instead add a parallel integer list of column numbers. The places that care about the pairing can chase both lists with forboth(), while the places that don't care just examine one list the same as before. The only real downside to this is that there are now two more lists that need to be passed to amcostestimate functions in case they care about column matching (which btcostestimate does, so not passing the info is not an option). Rather than deal with 11-argument amcostestimate functions, pass just the IndexPath and expect the functions to extract fields from it. That gets us down to 7 arguments which is better than 11, and it seems more future-proof against likely additions to the information we keep about an index path.
* Add bytea_agg, parallel to string_agg.Robert Haas2011-12-23

* Typo fixes.Robert Haas2011-12-22
| | | | All noted by Jaime Casanova.
* Add a security_barrier option for views.Robert Haas2011-12-22
| | | | | | | | | | | | | | When a view is marked as a security barrier, it will not be pulled up into the containing query, and no quals will be pushed down into it, so that no function or operator chosen by the user can be applied to rows not exposed by the view. Views not configured with this option cannot provide robust row-level security, but will perform far better. Patch by KaiGai Kohei; original problem report by Heikki Linnakangas (in October 2009!). Review (in earlier versions) by Noah Misch and others. Design advice by Tom Lane and myself. Further review and cleanup by me.
* Add ALTER DOMAIN ... RENAMEPeter Eisentraut2011-12-22
| | | | | | You could already rename domains using ALTER TYPE, but with this new command it is more consistent with how other commands treat domains as a subcategory of types.
* sepgsql: Check CREATE permissions for some object types.Robert Haas2011-12-21
| | | | KaiGai Kohei, reviewed by Dimitri Fontaine and me.
* Add support for privileges on typesPeter Eisentraut2011-12-20
| | | | | | | | | This adds support for the more or less SQL-conforming USAGE privilege on types and domains. The intent is to be able restrict which users can create dependencies on types, which restricts the way in which owners can alter types. reviewed by Yeb Havinga
* Allow CHECK constraints to be declared ONLYAlvaro Herrera2011-12-19
| | | | | | | | | | | | | This makes them enforceable only on the parent table, not on children tables. This is useful in various situations, per discussion involving people bitten by the restrictive behavior introduced in 8.4.

* Teach SP-GiST to do index-only scans.Tom Lane2011-12-19
| | | | | | | | | | | | Operator classes can specify whether or not they support this; this preserves the flexibility to use lossy representations within an index. In passing, move constant data about a given index into the rd_amcache cache area, instead of doing fresh lookups each time we start an index operation. This is mainly to try to make sure that spgcanreturn() has insignificant cost; I still don't have any proof that it matters for actual index accesses. Also, get rid of useless copying of FmgrInfo pointers; we can perfectly well use the relcache's versions in-place.
* Replace simple constant pg_am.amcanreturn with an AM support function.Tom Lane2011-12-18
| | | | | | | | | The need for this was debated when we put in the index-only-scan feature, but at the time we had no near-term expectation of having AMs that could support such scans for only some indexes; so we kept it simple. However, the SP-GiST AM forces the issue, so let's fix it. This patch only installs the new API; no behavior actually changes.
* Remove tabs in SGML file.Bruce Momjian2011-12-18

* Add SP-GiST (space-partitioned GiST) index access method.Tom Lane2011-12-17
| | | | | | | | | | | | SP-GiST is comparable to GiST in flexibility, but supports non-balanced partitioned search structures rather than balanced trees. As described at PGCon 2011, this new indexing structure can beat GiST in both index build time and query speed for search problems that it is well matched to. There are a number of areas that could still use improvement, but at this point the code seems committable. Teodor Sigaev and Oleg Bartunov, with considerable revisions by Tom Lane

* Add --section option to pg_dump and pg_restore.Andrew Dunstan2011-12-16
| | | | | | | | | Valid values are --pre-data, data and post-data. The option can be given more than once. --schema-only is equivalent to --section=pre-data --section=post-data. --data-only is equivalent to --section=data. Andrew Dunstan, reviewed by Joachim Wieland and Josh Berkus.

* include_if_exists facility for config file.Andrew Dunstan2011-12-15
| | | | | | | | This works the same as include, except that an error is not thrown if the file is missing. Instead the fact that it's missing is logged. Greg Smith, reviewed by Euler Taveira de Oliveira.

* Add --exclude-table-data option to pg_dump.Andrew Dunstan2011-12-14
| | | | | | | Andrew Dunstan, reviewed by Josh Berkus, Robert Haas and Peter Geoghegan. This allows dumping of a table definition but not its data, on a per table basis. Table name patterns are supported just as for --exclude-table.

* Remove spclocation field from pg_tablespaceMagnus Hagander2011-12-07
| | | | | | | | Instead, add a function pg_tablespace_location(oid) used to return the same information, and do this by reading the symbolic link. Doing it this way makes it possible to relocate a tablespace when the database is down by simply changing the symbolic link.
* Create a "sort support" interface API for faster sorting.Tom Lane2011-12-07
| | | | | | | | | | | | This patch creates an API whereby a btree index opclass can optionally provide non-SQL-callable support functions for sorting. In the initial patch, we only use this to provide a directly-callable comparator function, which can be invoked with a bit less overhead than the traditional SQL-callable comparator. While that should be of value in itself, the real reason for doing this is to provide a datatype-extensible framework for more aggressive optimizations, as in Peter Geoghegan's recent work. Robert Haas and Tom Lane
* Make command-line tools smarter about finding a DB to connect to.Robert Haas2011-12-06
| | | | | | | | If unable to connect to "postgres", try "template1". This allows things to work more smoothly in the case where the postgres database has been dropped. And just in case that's not good enough, also allow the user to specify a maintenance database to be used for the initial connection, to cover the case where neither postgres nor template1 is suitable.

* Add a \setenv command to psql.Andrew Dunstan2011-12-04
| | | | | | | | This can be used to set (or unset) environment variables that will affect programs called by psql (such as the PAGER), probably most usefully in a .psqlrc file. Andrew Dunstan, reviewed by Josh Kupershmidt.

* Add some weasel wording about threaded usage of PGresults.Tom Lane2011-12-02
| | | | | | PGresults used to be read-only from the application's viewpoint, but now that we've exposed various functions that allow modification of a PGresult, that sweeping statement is no longer accurate. Noted by Dmitriy Igrishin.
* Clarify documentation about SQL:2008 variant of LIMIT/OFFSET syntax.Tom Lane2011-12-01
