8f76324352 Report Python errors from iterators with PLy_elog
This improves reporting, as the error string now includes the actual
Python exception. As a side effect, this no longer sets the errcode to
ERRCODE_DATA_EXCEPTION, which might be considered a feature, as it's
not documented and not clear why iterator errors should be treated
differently.

1a4ab9ec23 If recovery_target_timeline is set to 'latest' and standby mode is enabled,
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.

4172bd8830 Suppress some "variable might be clobbered by longjmp" warnings.
Seen with an older gcc version.  I'm not sure these represent any real

volatile-marked variables in this code, so a couple more won't hurt.

a8a8a3e096 Efficient transaction-controlled synchronous replication.
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.

Casanova, Heikki Linnakangas and Robert Haas, plus the assistance
of many other design reviewers.

149b2673c2 Fix incorrect access to pg_index.indcollation.
Since this field is after a variable-length field, it can't simply be
accessed via the C struct for pg_index.  Fortunately, the relcache already
did the dirty work of pulling the information out to where it can be
accessed easily, so this is a one-line fix.

bfd7f8cbb2 Make plpythonu language use plpython2 shared library directly.
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.

ba0c93a0f4 Convert createlang/droplang to use CREATE/DROP EXTENSION.
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.

63b656b7bf Create extension infrastructure for the core procedural languages.
This mostly just involves creating control, install, and
update-from-unpackaged scripts for them.  However, I had to adjust plperl
and plpython to not share the same support functions between variants,
because we can't put the same function into multiple extensions.

catversion bump forced due to new contents of pg_pltemplate, and because
initdb now installs plpgsql as an extension not a bare language.

Add support for regression testing these as extensions not bare
languages.

Fix a couple of other issues that popped up while testing this: my initial
hack at pg_dump binary-upgrade support didn't work right, and we don't want
an extra schema permissions test after all.

Documentation changes still to come, but I'm committing now to see
whether the MSVC build scripts need work (likely they do).

b9cff97fdf Don't allow CREATE TABLE AS to create a column with invalid collation
It is possible that an expression ends up with a collatable type but
without a collation.  CREATE TABLE AS could then create a table based
on that.  But such a column cannot be dumped with valid SQL syntax, so
we disallow creating such a column.

8d3b421f5f Allow non-superusers to create (some) extensions.
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.

4442e1975d When creating a collation, check that the locales can be loaded
This is the same check that would happen later when the collation is
used, but it's friendlier to check the collation already when it is
created.

bd58d9d883 In initialize_SSL, don't fail unnecessarily when home dir is unavailable.
Instead, just act as though the certificate file(s) are not present.
There is only one case where this need be a hard failure condition: when
sslmode is verify-ca or verify-full, not having a root cert file is an
error.  Change the logic so that we complain only in that case, and
otherwise fall through cleanly.  This is how it used to behave pre-9.0,
but my patch 4ed4b6c54e of 2010-05-26 broke
the case.  Per report from Christian Kastner.

908ab80286 Further refine patch for commenting operator implementation functions.
Instead of manually maintaining the "implementation of XXX operator"
comments in pg_proc.h, delete all those entries and let initdb create
them via a join.  To let initdb figure out which name to use when there
is a conflict, change the comments for deprecated operators to say they
are deprecated --- which seems like a good thing to do anyway.

6252c4f9e2 Run a portal's cleanup hook immediately when pushing it to DONE state.
This works around the problem noted by Yamamoto Takashi in bug #5906,
that there were code paths whereby we could reach AtCleanup_Portals
with a portal's cleanup hook still unexecuted.  The changes I made
a few days ago were intended to prevent that from happening, and
I think that on balance it's still a good thing to avoid, so I don't
want to remove the Assert in AtCleanup_Portals.  Hence do this instead.
