2011-03-10Revert addition of third argument to format_type().Tom Lane
Including collation in the behavior of that function promotes a world view we do not want. Moreover, it was producing the wrong behavior for pg_dump anyway: what we want is to dump a COLLATE clause on attributes whose attcollation is different from the underlying type, and likewise for domains, and the function cannot do that for us. Doing it the hard way in pg_dump is a bit more tedious but produces more correct output. In passing, fix initdb so that the initial entry in pg_collation is properly pinned. It was droppable before :-(

2011-03-09Remove collation information from TypeName, where it does not belong.Tom Lane
The initial collations patch treated a COLLATE spec as part of a TypeName, following what can only be described as brain fade on the part of the SQL committee. It's a lot more reasonable to treat COLLATE as a syntactically separate object, so that it can be added in only the productions where it actually belongs, rather than needing to reject it in a boatload of places where it doesn't belong (something the original patch mostly failed to do). In addition this change lets us meet the spec's requirement to allow COLLATE anywhere in the clauses of a ColumnDef, and it avoids unfriendly behavior for constructs such as "foo::type COLLATE collation". To do this, pull collation information out of TypeName and put it in ColumnDef instead, thus reverting most of the collation-related changes in parse_type.c's API. I made one additional structural change, which was to use a ColumnDef as an intermediate node in AT_AlterColumnType AlterTableCmd nodes. This provides enough room to get rid of the "transform" wart in AlterTableCmd too, since the ColumnDef can carry the USING expression easily enough. Also fix some other minor bugs that have crept in in the same areas, like failure to copy recently-added fields of ColumnDef in copyfuncs.c. While at it, document the formerly secret ability to specify a collation in ALTER TABLE ALTER COLUMN TYPE, ALTER TYPE ADD ATTRIBUTE, and ALTER TYPE ALTER ATTRIBUTE TYPE; and correct some misstatements about what the default collation selection will be when COLLATE is omitted. BTW, the three-parameter form of format_type() should go away too, since it just contributes to the confusion in this area; but I'll do that in a separate patch.

2011-03-09Adjust the permissions required for COMMENT ON ROLE.Tom Lane
Formerly, any member of a role could change the role's comment, as of course could superusers; but holders of CREATEROLE privilege could not, unless they were also members. This led to the odd situation that a CREATEROLE holder could create a role but then could not comment on it. It also seems a bit dubious to let an unprivileged user change his own comment, let alone those of group roles he belongs to. So, change the rule to be "you must be superuser to comment on a superuser role, or hold CREATEROLE to comment on non-superuser roles". This is the same as the privilege check for creating/dropping roles, and thus fits much better with the rule for other object types, namely that only the owner of an object can comment on it. In passing, clean up the documentation for COMMENT a little bit. Per complaint from Owen Jacobson and subsequent discussion.

2011-03-07If recovery_target_timeline is set to 'latest' and standby mode is enabled,Heikki Linnakangas
periodically rescan the archive for new timelines, while waiting for new WAL segments to arrive. This allows you to set up a standby server that follows the TLI change if another standby server is promoted to master. Before this, you had to restart the standby server to make it notice the new timeline. This patch only scans the archive for TLI changes, it won't follow a TLI change in streaming replication. That is much needed too, but it would be a much bigger patch than I dare to sneak in this late in the release cycle. There was discussion on improving the sanity checking of the WAL segments so that the system would notice more reliably if the new timeline isn't an ancestor of the current one, but that is not included in this patch. Reviewed by Fujii Masao.

2011-03-06Efficient transaction-controlled synchronous replication.Simon Riggs
If a standby is broadcasting reply messages and we have named one or more standbys in synchronous_standby_names then allow users who set synchronous_replication to wait for commit, which then provides strict data integrity guarantees. Design avoids sending and receiving transaction state information so minimises bookkeeping overheads. We synchronize with the highest priority standby that is connected and ready to synchronize. Other standbys can be defined to takeover in case of standby failure. This version has very strict behaviour; more relaxed options may be added at a later date. Simon Riggs and Fujii Masao, with reviews by Yeb Havinga, Jaime Casanova, Heikki Linnakangas and Robert Haas, plus the assistance of many other design reviewers.
2011-03-05Adjust documentation about pg_pltemplate to reflect latest thinking.Tom Lane
It's more likely that pg_pltemplate will go away in the future than that we'll add additional specialized infrastructure for it.
2011-03-05Make plpythonu language use plpython2 shared library directly.Tom Lane
The original scheme for this was to symlink plpython.$DLSUFFIX to plpython2.$DLSUFFIX, but that doesn't work on Windows, and only accidentally failed to fail because of the way that CREATE LANGUAGE created or didn't create new C functions. My changes of yesterday exposed the weakness of that approach. To fix, get rid of the symlink and make pg_pltemplate show what's really going on.
2011-03-05Convert createlang/droplang to use CREATE/DROP EXTENSION.Tom Lane
In createlang this is a one-line change. In droplang there's a whole lot of cruft that can be discarded since the extension mechanism now manages removal of the language's support functions. Also, add deprecation notices to these two programs' reference pages, since per discussion we may toss them overboard altogether in a release or two.

2011-03-05Update documentation to reflect that standard PLs are now extensions.Tom Lane
Recommend use of CREATE EXTENSION rather than plain CREATE LANGUAGE where relevant. Encourage PL authors to provide extension wrappers for their PLs.
2011-03-04Allow non-superusers to create (some) extensions.Tom Lane
Remove the unconditional superuser permissions check in CREATE EXTENSION, and instead define a "superuser" extension property, which when false (not the default) skips the superuser permissions check. In this case the calling user only needs enough permissions to execute the commands in the extension's installation script. The superuser property is also enforced in the same way for ALTER EXTENSION UPDATE cases. In other ALTER EXTENSION cases and DROP EXTENSION, test ownership of the extension rather than superuserness. ALTER EXTENSION ADD/DROP needs to insist on ownership of the target object as well; to do that without duplicating code, refactor comment.c's big switch for permissions checks into a separate function in objectaddress.c. I also removed the superuserness checks in pg_available_extensions and related functions; there's no strong reason why everybody shouldn't be able to see that info. Also invent an IF NOT EXISTS variant of CREATE EXTENSION, and use that in pg_dump, so that dumps won't fail for installed-by-default extensions. We don't have any of those yet, but we will soon. This is all per discussion of wrapping the standard procedural languages into extensions. I'll make those changes in a separate commit; this is just putting the core infrastructure in place.
