would basically punt in all cases for 'foo <> ALL (array)', which resulted
in a performance regression for NOT IN compared to what we were doing in
8.1 and before.  Per report from Pavel Stehule.

after an error in a COPY statement.  Formerly it thought the COPY data
was SQL commands, and got quite confused.

relations: fix the executor so that we can have an Append plan on the
inside of a nestloop and still pass down outer index keys to index scans
within the Append, then generate such plans as if they were regular
inner indexscans.  This avoids the need to evaluate the outer relation
multiple times.

... in fact, it will be applied now in any query whatsoever.  I'm still
a bit concerned about the cycles that might be expended in failed proof
attempts, but given that CE is turned off by default, it's the user's
choice whether to expend those cycles or not.  (Possibly we should
change the simple bool constraint_exclusion parameter to something
more fine-grained?)

Added some default rules to lexer
Added log output to prepare statement
Added some more stuff to a test case

internally $$ strings are converted to single-quote strings.

In ecpg, output newlines in commands using standard C escapes, rather
than using literal newlines, which is not portable.

have the directory for the configure test.

thereby sharing code with the inheritance case.  This puts the UNION-ALL-view
approach to partitioned tables on par with inheritance, so far as constraint
exclusion is concerned: it works either way.  (Still need to update the docs
to say so.)  The definition of "simple UNION ALL" is a little simpler than
I would like --- basically the union arms can only be SELECT * FROM foo
--- but it's good enough for partitioned-table cases.

MemSet on AIX by setting MEMSET_LOOP_LIMIT to zero.

Add optimization to skip MemSet tests in MEMSET_LOOP_LIMIT == 0 case and
just call memset() directly.

Disallow backslash as the delimiter in non-CVS mode.

Backpatch.

it later.  This fixes a problem where EXEC_BACKEND didn't have progname
set, causing a segfault if log_min_messages was set below debug2 and our
own snprintf.c was being used.

Also alway strdup() progname.

Backpatch to 8.1.X and 8.0.X.
