chdir into PGDATA and subsequently use relative paths instead of absolute
paths to access all files under PGDATA.  This seems to give a small
performance improvement, and it should make the system more robust
against naive DBAs doing things like moving a database directory that
has a live postmaster in it.  Per recent discussion.

You were correct. This patch fixes it.

auto-detection of AES.

Now openssl.c just checks OpenSSL version.  Whoever compiles
newer OpenSSL without AES is on his own.

able to do this before, but I had tried to make an exception for functions
with OUT parameters.  Michael Fuhr found one problem with it already, and
I found another, which was it didn't work for strict functions with a
NULL input.  While both of these could be worked around, the probability
that there are more gotchas seems high; I think prudence dictates just
reverting to the former behavior for now.  Accordingly, remove the kluge
added to get_expr_result_type() for Michael's case.

relies on the output of zic being platform independent, but that is
currently the case.

through multiple join clauses.

(currently in beta) when cryptolib = openssl.  According to the
following checkin message from several years ago, OpenSSL application
developers should no longer rely on <openssl/evp.h> to include
everything they need:

http://cvs.openssl.org/chngview?cn=9888

This patch adds the necessary header files.  It doesn't appear to
break anything when building against OpenSSL 0.9.7.

BTW, core appears to build and work fine with OpenSSL 0.9.8.  I've
built 7.3 through HEAD against 0.9.8-beta6 without noticing any
problems.

propagated inside an outer join.  In particular, given
LEFT JOIN ON (A = B) WHERE A = constant, we cannot conclude that
B = constant at the top level (B might be null instead), but we
can nonetheless put a restriction B = constant into the quals for
B's relation, since no inner-side rows not meeting that condition
can contribute to the final result.  Similarly, given
FULL JOIN USING (J) WHERE J = constant, we can't directly conclude
that either input J variable = constant, but it's OK to push such
quals into each input rel.  Per recent gripe from Kim Bisgaard.
Along the way, remove 'valid_everywhere' flag from RestrictInfo,
as on closer analysis it was not being used for anything, and was
defined backwards anyway.

I took the opportunity to add an rtree-equivalent gist opclass for
circles; the contrib version only covered boxes and polygons, but
indexing circles is very handy for distance searches.

non-NULL in this function, so there is no need to check for it (2) we

Astor at EnterpriseDB, with slight cleanup by myself, per a report
from the Coverity tool.

- add forgotten check of lsn for insert completion
- remove level of pages: hard to check in recovery
- some cleanups
