an expression that's not supposed to contain variables.  Per discussion
with Gevik Babakhani, this eliminates the need for an ugly kluge (namely,
specifying some unrelated relation name).  Remove one such kluge from
pg_dump.

reason to fail, and their callers were mostly not checking anyway.

This is potentially a back-patchable bug fix, but for the moment it doesn't
seem sufficiently high impact to justify doing that.

relopt_kind value in add_reloption_kind().  Per Zdenek Kotala.

this case is worth a special code path, but a special code path that gets
the boundary condition wrong is definitely no good.  Per bug #4821 from
Andrew Gierth.

In passing, clean up some minor code formatting issues (excess parentheses
and blank lines in odd places).

Back-patch to 8.3, where the bug was introduced.

Basically, it's needed to support binary dump from 8.3 because ordering rule
was changed.

there's no analyzable attributes or indexes. We also used to report 0 live

calculations.

This fixes bug #4812 reported by George Su. Backpatch back to 8.1.

as was intended.  I broke this behavior recently by installing atexit
callbacks without thinking about the one case where we truly don't want
to run those callback functions.  Noted in an example from Dave Page.

is run at the end of archive recovery, providing a chance to do external
cleanup. Modify pg_standby so that it no longer removes the trigger file,
that is to be done using the recovery_end_command now.

Provide a "smart" failover mode in pg_standby, where we don't fail over
immediately, but only after recovering all unapplied WAL from the archive.
That gives you zero data loss assuming all WAL was archived before
failover, which is what most users of pg_standby actually want.

that aren't RELKIND_RELATION or RELKIND_VIEW, and to disallow attaching rules
to system relations unless allowSystemTableMods is on.  This is to make the
behavior of CREATE RULE more like CREATE TRIGGER, which disallows the
comparable cases.  Per discussion of bug #4808.
