patch, but it didn't fix the whole issue.

The same bug is present in older releases as well, but the 8.4 train is
about to leave the station, and I'm not sure if have consensus on whether
we can remove the -l option in back-branches or do we need to attempt a
server-side fix to make symlinking safe.

create an ABI break between 8.3 and 8.4.  It is still just a wrapper around
the built-in current_query() function, but at a different implementation
level.  Per my proposal.

Note: this change doesn't break 8.4beta installations, since their
SQL-language definition of the function still works fine.

issue raised by Ruzsinszky Attila and confirmed by others.

 ----------------------------------------------------------------------

The original implementation of the 3-argument form of get_raw_page() risked
core dumps if the 8.3 SQL function definition was mistakenly used with the
8.4 module, which is entirely likely after a dump-and-reload upgrade.  To
protect 8.4 beta testers against upgrade problems, add a check on PG_NARGS.

In passing, fix missed additions to the uninstall script, and polish the
docs a trifle.

the <@ and @> operators.  These are not in fact equivalent to the built-in
anyarray operators of the same names, because they have different behavior for
empty arrays, namely they don't think empty arrays are contained in anything.
That is mathematically wrong, no doubt, but until we can persuade GIN indexes
to implement the mathematical definition we should probably not change this.
Another reason for not changing it now is that we can't yet ensure the
opclasses will be updated correctly in a dump-and-reload upgrade.  Per
recent discussions.

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.

pgbench_history, and pgbench_tellers, rather than just accounts, branches,

remove the automatic "SET search_path = public" that it did at startup,
as this seems to restrict testing flexibility without actually buying much.

don't cause confusion with the built-in anyarray versions of those operators.
Adjust the module's index opclasses to support the built-in operators in place
of the private ones.

The private implementations are still available under their historical
names @ and ~, so no functionality is lost.  Some quick testing suggests
that they offer no real benefit over the core operators, however.

This is the core infrastructure needed to support the soon-to-appear
contrib/btree_gin module.  The APIs are still upward compatible with the
definitions used in 8.3 and before, although *not* with the previous 8.4devel
function definitions.

Presumably core dumps on SIGQUIT are not a problem on Windows, so rather
