For win32 in general, this makes it possible to run the regression tests
as an admin user by using the same restricted token method that's used
by pg_ctl and initdb.

For vc++, it adds building of pg_regress.exe, adds a resultmap, and
fixes how it runs the install.

will overwrite the buffer by one byte.

Also add some strlcpy() to eliminate some weird memory handling.

Assume "TM" when input fields are variable-length, like month or day
names.  This matches Oracle behavior.

already collected in the current transaction; this allows plpgsql functions to
watch for stats updates even though they are confined to a single transaction.
Use this instead of the previous kluge involving pg_stat_file() to wait for
the stats collector to update in the stats regression test.  Internally,
decouple storage of stats snapshots from transaction boundaries; they'll
now stick around until someone calls pgstat_clear_snapshot --- which xact.c
still does at transaction end, to maintain the previous behavior.  This makes
the logic a lot cleaner, at the price of a couple dozen cycles per transaction
exit.

changes (with an upper limit of 30 seconds), and record the delay time in
the postmaster log.  This should give us some info about what's happening
with the intermittent stats failures in buildfarm.  After an idea of
Andrew Dunstan's.

postmaster when it really is ready to accept connections.  Per proposal from
Markus Schiltknecht and subsequent discussion.

strange coding practices.

thought that it didn't have to reposition the underlying tuplestore if the
portal is atEnd.  But this is not so, because tuplestores have separate read
and write cursors ... and the read cursor hasn't moved from the start.
This mistake explains bug #2970 from William Zhang.

Note: the coding here is pretty inefficient, but given that no one has noticed
this bug until now, I'd say hardly anyone uses the case where the cursor has
been advanced before being persisted.  So maybe it's not worth worrying about.

    <P>USA saving time changes are included in PostgreSQL release 8.0.[4+],
    and all later major releases, e.g. 8.1.  Canada and Western Australia
    changes are included in 8.0.[10+], 8.1.[6+], and all later major
    releases.  PostgreSQL releases prior to 8.0 use the operating system's
    timezone database for daylight saving information.</P>

out that ExecEvalVar and friends don't necessarily have access to a tuple
descriptor with correct typmod: it definitely can contain -1, and possibly
might contain other values that are different from the Var's value.
Arguably this should be cleaned up someday, but it's not a simple change,
and in any case typmod discrepancies don't pose a security hazard.
Per reports from numerous people :-(

I'm not entirely sure whether the failure can occur in 8.0 --- the simple
test cases reported so far don't trigger it there.  But back-patch the
change all the way anyway.

it's no longer necessary to make it accessible to clients.

because I had gotten rid of the simplify_jointree() preprocessing step, and
optimize_minmax_aggregates() wasn't smart enough to deal with a non-canonical

Pass modern COPY syntax to backend, since copy (query) does not accept old syntax. Per complaint from Michael Fuhr.

describe the maximum size of index tuples (which is typically AM-dependent
anyway); and consequently remove the bogus deduction for "special space"
that was built into it.

Adjust TOAST_TUPLE_THRESHOLD and TOAST_MAX_CHUNK_SIZE to avoid wasting two
bytes per toast chunk, and to ensure that the calculation correctly tracks any
future changes in page header size.  The computation had been inaccurate in a
way that didn't cause any harm except space wastage, but future changes could
have broken it more drastically.

Fix the calculation of BTMaxItemSize, which was formerly computed as 1 byte
more than it could safely be.  This didn't cause any harm in practice because
it's only compared against maxalign'd lengths, but future changes in the size
of page headers or btree special space could have exposed the problem.

initdb forced because of change in TOAST_MAX_CHUNK_SIZE, which alters the
storage of toast tables.
