it was using too soon.  In a situation where pg_do_encoding_conversion is
a no-op, this led to garbage data returned.

In HEAD, also modify the code that's ensuring null termination to make it
a tad more obvious what's happening.

VACUUM reset them to false rather than trying to clean 'em up during DROP.

("there might be triggers") rather than an exact count.  This is necessary
catalog infrastructure for the upcoming patch to reduce the strength of
locking needed for trigger addition/removal.  Split out and committed
separately for ease of reviewing/testing.

In passing, also get rid of the unused pg_class columns relukeys, relfkeys,
and relrefs, which haven't been maintained in many years and now have no
chance of ever being maintained (because of wishing to avoid locking).

If the latter doesn't exist, automatically recreate it.  (We don't do
this for pg_xlog, though, per discussion.)

(It's always worked like this, but we never documented it before.)

from DateStyle, and create a new interval style that produces output matching
the SQL standard (at least for interval values that fall within the standard's
restrictions).  IntervalStyle is also used to resolve the conflict between the
standard and traditional Postgres rules for interpreting negative interval
input.

it behaves correctly for a leading minus sign, zero year value, and
nonzero month value.  Per discussion with Ron Mayer.

citext-to-and-from-xml tests, since those caused variation between

repurpose citext_1.out as the expected results in glibc en_US (and probably
other) locales.

(but not locked, as that would risk deadlocks).  Also, make it work in a small
ring of buffers to avoid having bulk inserts trash the whole buffer arena.

Robert Haas, after an idea of Simon Riggs'.

if their source or target types match the pattern (using the same definition
of "match" as \dT does).  Per recent discussion.

index column numbers needs to handle the case where you have more than
one scankey on the same index column. toast_fetch_datum_slice() needs it.

change fix for suppress_redundant_updates_trigger() where relation has Oids, to only apply if present Oid is invalid, per second thought from TGL

Hopefully this will forestall future confusion about their roles.
