We should probably have a better way to do this (meaning
something not hardcoded) eventually, but this fixes the
problem for 8.4.

they won't be indexing off the ends of static arrays.

that pg_start_backup() takes a long time even when there's no need to minimize
its I/O consumption.

negligible --- what I'm interested in is making sure that if we have
second thoughts about the definition, we will not have to force a
post-beta initdb to change the implementation.

of discovery, rather than reverse order.  This doesn't matter functionally
(I suppose the previous coding dates from the time when lcons was markedly
cheaper than lappend).  However now that EXPLAIN is labeling subplans with
IDs that are based on order of creation, this may help produce a slightly
less surprising printout.

are individually labeled, rather than just grouped under an "InitPlan"
or "SubPlan" heading.  This in turn makes it possible for decompilation of
a subplan reference to usefully identify which subplan it's referencing.
I also made InitPlans identify which parameter symbol(s) they compute,
so that references to those parameters elsewhere in the plan tree can
be connected to the initplan that will be executed.  Per a gripe from
Robert Haas about EXPLAIN output of a WITH query being inadequate,
plus some longstanding pet peeves of my own.

Improve comments. Now GIN-indexable operators should be strict.

are using our own ports of getopt or getopt_long, those will define
the variable for themselves; and if not, we don't need these, because
we never touch the variable anyway.

does not; it was only because getopt.c defined the variable anyway
that things failed to fall over.

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.

Per a complaint from Rusty Conover.

probe for opterr (exactly like the one for optreset) and have getopt.c
define the variables only if configure doesn't find them in libc.

of adding optional namespace and action fields to DefElem.  Having three
node types that do essentially the same thing bloats the code and leads
to errors of confusion, such as in yesterday's bug report from Khee Chin.

when we are waiting for old snapshots to go away during a concurrent index
build.  In particular, this rule lets us avoid waiting for
idle-in-transaction sessions.

This logic could be improved further if we had some way to wake up when
the session we are currently waiting for goes idle-in-transaction.  However
that would be a significantly more complex/invasive patch, so it'll have to
wait for some other day.

interval_eq() considers equal.  I'm not sure how that fundamental requirement
escaped us through multiple revisions of this hash function, but there it is;
it's been wrong since interval_hash was first written for PG 7.1.
Per bug #4748 from Roman Kononov.

Backpatch to all supported releases.

This patch changes the contents of hash indexes for interval columns.  That's
no particular problem for PG 8.4, since we've broken on-disk compatibility
of hash indexes already; but it will require a migration warning note in
the next minor releases of all existing branches: "if you have any hash
indexes on columns of type interval, REINDEX them after updating".

To implement this without almost duplicating the reloption table, treat
relopt_kind as a bitmask instead of an integer value.  This decreases the
range of allowed values, but it's not clear that there's need for that much
values anyway.

This patch also makes heap_reloptions explicitly a no-op for relation kinds
other than heap and TOAST tables.

Patch by ITAGAKI Takahiro with minor edits from me.  (In particular I removed
the bit about adding relation kind to an error message, which I intend to
commit separately.)

TOAST tables and indexes; to wit, never show either.  (You can
examine them with plain \d if you're really so inclined.)
