Stephen Frost	fd321a1dfd	Remove superuser checks in pgstattuple Now that we track initial privileges on extension objects and changes to those permissions, we can drop the superuser() checks from the various functions which are part of the pgstattuple extension and rely on the GRANT system to control access to those functions. Since a pg_upgrade will preserve the version of the extension which existed prior to the upgrade, we can't simply modify the existing functions but instead need to create new functions which remove the checks and update the SQL-level functions to use the new functions (and to REVOKE EXECUTE rights on those functions from PUBLIC). Thanks to Tom and Andres for adding support for extensions to follow update paths (see: `40b449a`), allowing this patch to be much smaller since no new base version script needed to be included. Approach suggested by Noah. Reviewed by Michael Paquier.	9 years ago
Robert Haas	a8501ba119	Update pgstattuple extension for parallel query. All functions provided by this extension are PARALLEL SAFE. Andreas Karlsson	9 years ago
Andres Freund	5850b20f58	Add pgstattuple_approx() to the pgstattuple extension. The new function allows to estimate bloat and other table level statics in a faster, but approximate, way. It does so by using information from the free space map for pages marked as all visible in the visibility map. The rest of the table is actually read and free space/bloat is measured accurately. In many cases that allows to get bloat information much quicker, causing less IO.

Fujii Masao	1dc118660b	Fix pgstattuple functions to use regclass-type as the argument. This allows us to specify the target relation with several expressions, 'relname', 'schemaname.relname' and OID in all pgstattuple functions. pgstatindex() and pg_relpages() could not accept OID as the argument so far. Per discussion on -hackers, we decided to keep two types of interfaces, with regclass-type and TEXT-type argument, for each pgstattuple function because of the backward-compatibility issue. The functions which have TEXT-type argument will be deprecated in the future release. Patch by Satoshi Nagayasu, reviewed by Rushabh Lathia and Fujii Masao.	12 years ago

Tom Lane	629b3af27d	Convert contrib modules to use the extension facility. This isn't fully tested as yet, in particular I'm not sure that the "foo--unpackaged--1.0.sql" scripts are OK. But it's time to get some buildfarm cycles on it. sepgsql is not converted to an extension, mainly because it seems to require a very nonstandard installation process.
