The default values for shared_buffers and max_connections are now 1000
and 100 respectively, if the platform will allow it. initdb selects
values that are not too large to allow the postmaster to start, and
places these values in the installed postgresql.conf file. This allows
us to continue to start up out-of-the-box on platforms with small SHMMAX,
while having somewhat-realistic default settings on platforms with
reasonable SHMMAX. Per recent pghackers discussion.

tm2timestamp should return -1, not elog, on overflow. (In the backend

Do honest transformation and preprocessing of LIMIT/OFFSET clauses,
instead of the former kluge whereby gram.y emitted already-transformed
expressions. This is needed so that Params appearing in these clauses
actually work correctly. I suppose some might claim that the side effect
of 'SELECT ... LIMIT 2+2' working is a new feature, but I say this is

Aggregates can be polymorphic, using polymorphic implementation functions.

lacking. By Joe Conway, with some kibitzing from Tom Lane.

Restructure building of join relation targetlists so that a join plan
node emits only those vars that are actually needed above it in the
plan tree. (There were comments in the code suggesting that this was
done at some point in the dim past, but for a long time we have just
made join nodes emit everything that either input emitted.) Aside from
being marginally more efficient, this fixes the problem noted by Peter
Eisentraut where a join above an IN-implemented-as-join might fail,
because the subplan targetlist constructed in the latter case didn't
meet the expectation of including everything.
Along the way, fix some places that were O(N^2) in the targetlist
length. This is not all the trouble spots for wide queries by any
means, but it's a step forward.

- Made sure Informix style decimal vars are initialized. They use a

around. PostgreSQL numeric type remains the same.

hold". Is this really they way SE behaves?

Support expressions of the form 'scalar op ANY (array)' and
'scalar op ALL (array)', where the operator is applied between the
lefthand scalar and each element of the array. The operator must
yield boolean; the result of the construct is the OR or AND of the
per-element results, respectively.

transaction status. Add a VERBOSE variable to control verboseness
