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).

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).

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.

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.

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...

blanks, in hopes of reducing the surprise factor for newbies. Remove
redundant operators for VARCHAR (it depends wholly on TEXT operations now).
Clean up resolution of ambiguous operators/functions to avoid surprising
choices for domains: domains are treated as equivalent to their base types
and binary-coercibility is no longer considered a preference item when
choosing among multiple operators/functions. IsBinaryCoercible now correctly
reflects the notion that you need *only* relabel the type to get from type
A to type B: that is, a domain is binary-coercible to its base type, but
not vice versa. Various marginal cleanup, including merging the essentially
duplicate resolution code in parse_func.c and parse_oper.c. Improve opr_sanity
regression test to understand about binary compatibility (using pg_cast),
and fix a couple of small errors in the catalogs revealed thereby.
Restructure "special operator" handling to fetch operators via index opclasses
rather than hardwiring assumptions about names (cleans up the pattern_ops
stuff a little).

single-byte encodings, and a direct C implementation of the single-argument
forms (where spaces are always what gets trimmed). This is in preparation
for using rtrim1() as the bpchar-to-text cast operator, but is a useful
performance improvement even if we decide not to do that.

Also run autoheader, which seems not to have been done lately;
it added about three more things to pg_config.h.in than I was expecting...

example from Rao Kumar. This is a very corner corner-case, requiring
a minimum of three closely-spaced database crashes and an unlucky
positioning of the second recovery's checkpoint record before you'd notice
any problem. But the consequences are dire enough that it's a must-fix.
