Per request from Marc Munro.

testing ownership if the caller isn't interested in any GOPTION bits
(which is the common case).  It did not matter in 8.0 where the ownership
test was just a trivial equality test, but it matters now.

level for unrecognized win32 error codes to LOG, and make messages
conform to style guide.  Per old suggestion from Qingqing Zhou, which
seems to have gotten lost in the shuffle.

Remove unportable use of tfind/tsearch in favor of bsearch.  Fix up
random number generator to use random() not rand() and to actually honor
its min/max arguments properly.  That wasn't so important before, but
with exposure of capability to ask for general ranges, it will be.

CREATE TABLE command, and translate dBase's 'M' field type to 'text'.

cache lookup in the success case.  This won't help much for cases where
the given relation is far down the search path, but it does not hurt in
any cases either; and it requires only a little new code.  Per gripe from
Jim Nasby about slowness of \d with many tables.

current backend in pg_listener, so there is little point in making
the PID to register part of async.c's public API. Other minor tweaks.

the parameter's name (if any) as the default column name for SELECT FROM
the function, rather than the function name as previously.  I still think
this is a bad idea, but I lost the argument.  Force decompilation of
function RTEs to specify full aliases always, to reduce the odds of this
decision breaking dumped views.

predicate_implied_by() to detect redundant filter conditions, but forgot
that predicate_implied_by() assumes its first argument contains only
immutable functions.  Add a check to guarantee that.  Also, test to see
if filter conditions can be discarded because they are redundant with
the predicate of a partial index.

generated by bitmap index scans.  Along the way, simplify and speed up
the code for counting sequential and index scans; it was both confusing
and inefficient to be taking care of that in the per-tuple loops, IMHO.
initdb forced because of internal changes in pg_stat view definitions.

fixes by Neil Conway.

comment, it can at least test whether the expression returns set.

Make pgbench "script driven" to eliminate hard coded transaction
scenario. (Tatsuo Ishii)

Somehow I missed some parser changes, so this commit comes pretty late. I just synced the parser of ecpg against the backend version, but still have to sync the lexer.

Also I fixed a bug in a bug fix I committed a few weeks ago. he check for a varchar pointer was incomplete.

Per buildfarm results and Michael Fuhr.
