Enable CHECK constraints to be declared NOT VALID
This means that they can initially be added to a large existing table
without checking its initial contents, but new tuples must comply to
them; a separate pass invoked by ALTER TABLE / VALIDATE can verify
existing data and ensure it complies with the constraint, at which point
it is marked validated and becomes a normal part of the table ecosystem.

constraint_exclusion purposes; when validated, cached plans are

Move the PredicateLockRelation() call from nodeSeqscan.c to heapam.c. It's
more consistent that way, since all the other PredicateLock* calls are
made in various heapam.c and index AM functions. The call in nodeSeqscan.c
was unnecessarily aggressive anyway, there's no need to try to lock the
relation every time a tuple is fetched, it's enough to do it once.
This has the user-visible effect that if a seq scan is initialized in the
executor, but never executed, we now acquire the predicate lock on the heap
relation anyway. We could avoid that by taking the lock on the first
heap_getnext() call instead, but it doesn't seem worth the trouble given
that it feels more natural to do it in heap_beginscan().
Also, remove the retail PredicateLockTuple() calls from heap_getnext(). In

Modernise pg_hba.conf token processing
The previous coding was ugly, as it marked special tokens as such in the
wrong stage, relying on workarounds to figure out if they had been

for example. Fix by restructuring the parser code so that it remembers
whether tokens were quoted or not. This eliminates widespread knowledge
of possible known keywords for all fields.
Also improve memory management in this area, to use memory contexts that
are reset as a whole instead of using retail pfrees; this removes a
whole lotta crufty (and probably slow) code.
Instead of calling strlen() three times in next_field_expand on the
returned token to find out whether there was a comma (and strip it),

Fix symlink for errcodes.h so it works in VPATH builds from tarballs.
backend/Makefile was treating errcodes.h as a header always generated

Remove pointless const qualifiers from function arguments in the SSI code.
As Tom Lane pointed out, "const Relation foo" doesn't guarantee that you
can't modify the data the "foo" pointer points to. It just means that you
can't change the pointer to point to something else within the function,
which is not very useful.

Make the visibility map crash-safe.
This involves two main changes from the previous behavior. First,
when we set a bit in the visibility map, emit a new WAL record of type
XLOG_HEAP2_VISIBLE. Replay sets the page-level PD_ALL_VISIBLE bit and
the visibility map bit. Second, when inserting, updating, or deleting
a tuple, we can no longer get away with clearing the visibility map
bit after releasing the lock on the corresponding heap page, because
an intervening crash might leave the visibility map bit set and the
page-level bit clear. Making this work requires a bit of interface
refactoring.
In passing, a few minor but related cleanups: change the test in
visibilitymap_set and visibilitymap_clear to throw an error if the
wrong page (or no page) is pinned, rather than silently doing nothing;
this case should never occur. Also, remove duplicate definitions of
InvalidXLogRecPtr.

Make deadlock_timeout PGC_SUSET rather than PGC_SIGHUP.
This allows deadlock_timeout to be reduced for transactions that are
particularly likely to be involved in a deadlock, thus detecting it
more quickly. It is also potentially useful as a poor-man's deadlock
priority mechanism: a transaction with a high deadlock_timeout is less
likely to be chosen as the victim than one with a low
deadlock_timeout. Since that could be used to game the system, we
make this PGC_SUSET rather than PGC_USERSET.
At some point, it might be worth thinking about a more explicit
priority mechanism, since using this is far from fool-proof. But
let's see whether there's enough use case to justify the additional
work before we go down that route.

Add notion of a "transform function" that can simplify function calls.
Initially, we use this only to eliminate calls to the varchar()
function in cases where the length is not being reduced and, therefore,
the function call is equivalent to a RelabelType operation. The most
significant effect of this is that we can avoid a table rewrite when
changing a varchar(X) column to a varchar(Y) column, where Y > X.

Apply upstream fix for blowfish signed-character bug (CVE-2011-2483).
A password containing a character with the high bit set was misprocessed
on machines where char is signed (which is most). This could cause the
preceding one to three characters to fail to affect the hashed result,
thus weakening the password. The result was also unportable, and failed
to match some other blowfish implementations such as OpenBSD's.
Since the fix changes the output for such passwords, upstream chose
to provide a compatibility hack: password salts beginning with $2x$
(instead of the usual $2a$ for blowfish) are intentionally processed
"wrong" to give the same hash as before. Stored password hashes can
thus be modified if necessary to still match, though it'd be better
to change any affected passwords.
In passing, sync a couple other upstream changes that marginally improve
performance and/or tighten error checking.
Back-patch to all supported branches. Since this issue is already
public, no reason not to commit the fix ASAP.
