The vars are renamed to data_directory, config_file, hba_file, and
ident_file, and are guaranteed to be set to accurate absolute paths
during postmaster startup.
This commit does not yet do anything about hiding path values from
non-superusers.
PROMPT2 and PROMPT3 variables before we read any of the settings specified
via the user on the command-line or in psqlrc, so that the latter can
override the former. Per original patch from Ingo van Lil, simpler fix
suggested by Tom Lane.
Refactor code into something reasonably understandable, cause
use of the feature to not fail in standalone backends or in
EXEC_BACKEND case, fix sloppy guc.c table entries, make the
documentation minimally usable.
list elements comma-separated instead of barfing. This allows elimination
of half a dozen redundant copies of that behavior, and also makes the
world safe again for pg_get_expr() applied to pg_index.indexprs, per gripe
from Alexander Zhiltsov.
columns. The returned tuple needs to have appropriate NULL columns
inserted so that it actually matches the declared rowtype. It seemed
convenient to use a JunkFilter for this, so I made some cleanups and
simplifications in the JunkFilter code to allow it to support this
additional functionality. (That in turn exposed a latent bug in
nodeAppend.c, which is that it was returning a tuple slot whose
descriptor didn't match its data.) Also, move check_sql_fn_retval
out of pg_proc.c and into functions.c, where it seems to more naturally
belong.
* We are not sure how much precision is in tv_usec, so we
* swap the high and low 16 bits of 'later' and XOR them with
* 'earlier'. On the off chance that the result is 0, we
* loop until it isn't.

different backends get a reasonably wide set of initial seeds even if
gettimeofday returns tv_usec values with only a few bits of precision.
Per recent discussion.
* Links with -leay32 and -lssleay32 instead of crypto and ssl. On win32,
"crypto and ssl" is only used for static linking.
* Initializes SSL in the backend and not just in the postmaster. We
cannot pass the SSL context from the postmaster through the parameter
file, because it contains function pointers.
* Split one error check in be-secure.c. Previously we could not tell
which of three calls actually failed. The previous code also returned
incorrect error messages if SSL_accept() failed - that function needs to
use SSL_get_error() on the return value, can't just use the error queue.
* Since the win32 implementation uses non-blocking sockets "behind the
scenes" in order to deliver signals correctly, implements a version of
SSL_accept() that can handle this. Also, add a wait function in case
SSL_read or SSL_write() needs more data.
