when the plan is ReScanned, we don't have to rebuild the hash table
if there is no parameter change for its child node.  This idea has
been used for a long time in Sort and Material nodes, but was not in
the hash code till now.

yy_fatal_error() call results in elog(ERROR) not exit().  This was
already fixed in the main lexer and plpgsql, but extend same technique
to all the other dot-l files.  Also, on review of the possible calls
to yy_fatal_error(), it seems safe to use elog(ERROR) not elog(FATAL).

for grammar-detected problems.  Revert Makefile hack that kept it looking
like the pre-bison-1.875 output.

leave it for the kernel to do after the process dies.  This allows clients
to wait for the backend to exit if they wish (after sending X message,
wait till EOF is detected on the socket).

need -fPIC on HPPA.  Reduce to -fpic.

progress, although all RTs pass using the V3 protocol on a 7.4 database and also pass using the V2 protocol on a 7.3 database.
SSL support is known not to work.

introducing new 'FastList' list-construction subroutines to use in
hot spots.  This avoids the O(N^2) behavior of repeated lappend's
by keeping a tail pointer, while not changing behavior by reversing
list order as the lcons() method would do.

in initdb will result in exit(1), allowing the initdb script to realize
that there's something wrong.

of order; the 'server log' output is actually client output in these
scenarios and we ought to treat elevels the same way as in the client
case.  This allows initdb to not send backend stderr to /dev/null anymore,
which makes it much more likely that people will notice problems during
initdb.

of an index can now be a computed expression instead of a simple variable.
Restrictions on expressions are the same as for predicates (only immutable
functions, no sub-selects).  This fixes problems recently introduced with
inlining SQL functions, because the inlining transformation is applied to
both expression trees so the planner can still match them up.  Along the
way, improve efficiency of handling index predicates (both predicates and
index expressions are now cached by the relcache) and fix 7.3 oversight
that didn't record dependencies of predicate expressions.

users can't turn it off.

docs that CLIENT/LOG_MIN_MESSAGES now controls debug_* output location.
Doc changes included.

advertised in RowDescription message.  Depending on the physical tuple's
column count is not really correct, since according to heap_getattr()
conventions the tuple may be short some columns, which will automatically
get read as nulls.  Problem has been latent since forever, but was only
exposed by recent change to skip a projection step in SELECT * FROM...

Also clean up wording that command line utils need database access.
