"verify-ca" and "verify-full".
Since "prefer" remains the default, this will make certificate validation
off by default, which should lead to less upgrade issues.

it's implemented, but accepted too much/too little compared to
the API documentation.
Per comment from Zdenek Kotala.
now always use the system username as the default, and not try to pick it up
from the kerberos ticket.
This fixes the spurious error messages that show up on kerberos-enabled builds
when not actually using kerberos, and puts it in line with how other authentication
methods work.
empty query string is passed to PQexecParams and related functions. Its
handling of the NoData response to Describe messages was subtly incorrect.
Per my report of yesterday.
Although I consider this a bug, it's a behavioral change that might affect
applications, so not back-patched.
In passing fix a second issue in the same code: it didn't react well to an
out-of-memory failure while trying to make the PGresult object.

it's connection. This is required for applications that unload
the libpq library (such as PHP) in which case we'd otherwise
have pointers to these functions when they no longer exist.
This needs a bit more testing before we can consider a backpatch,
so not doing that yet.
In passing, remove unused functions in backend/libpq.

Since this means we no longer need fnmatch, remove the imported implementation

results (ie, an empty "broken" buffer) if memory overrun occurs anywhere
along the way to filling the buffer. The previous coding would just silently
discard portions of the intended buffer contents, as exhibited in trouble

and report such overruns. There's probably much more that should be done
in this line, but this is a start.
libpq. As noted by Peter, adding this variable created a risk of unexpected
connection failures when talking to older server versions, and since it
doesn't do anything you can't do with PGOPTIONS, it doesn't seem really
necessary. Removing it does occasion a few extra lines in pg_regress.c,
but saving a getenv() call per libpq connection attempt is perhaps worth
that anyway.
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.

after each other (since we already add a newline on each, this makes them
multiline).
Previously a new error would just overwrite the old one, so for example any
error caused when trying to connect with SSL enabled would be overwritten
by the error message form the non-SSL connection when using sslmode=prefer.
that presence of the password in the conninfo string must be checked *before*
risking a connection attempt, there is no point in checking it afterwards.
This makes the specification of PQconnectionUsedPassword() a bit simpler
and perhaps more generally useful, too.
conninfo string *before* trying to connect to the remote server, not after.
As pointed out by Marko Kreen, in certain not-very-plausible situations
this could result in sending a password from the postgres user's .pgpass file,
or other places that non-superusers shouldn't have access to, to an
untrustworthy remote server. The cleanest fix seems to be to expose libpq's
conninfo-string-parsing code so that dblink can check for a password option
without duplicating the parsing logic.

They no longer need to defend themselves against getting a DESTROY

Per Microsoft knowledge base article Q201213, early versions of
Windows fail when we do this. Later versions of Windows appear
to have a higher limit than 64Kb, but do still fail on large
sends, so we unconditionally limit it for all versions.
