I put some extra checks to make sure a query was a good candidate for
rewrite into a UNION.    Besides the existing checks:

1.  Make sure the AND/OR tree was rectangular.  ( i.e.    3 X 4  or 10 X
3)
2.  Only one table.
3.  Must have an AND dimension.
4.  At least 9 OP expressions total

Also  cleaned up and commented.

 supplied by a DEFAULT clause.  Enables INSERT INTO TABLE DEFAULT VALUES...

 Should be done every time gram.c is refreshed.

I will be cleaning this up more before the Oct 1 deadline.

David Hartwig.  AND/OR fix.

Sorry, I didn't know it is a GNU extension. I have written this patch
which should fix the problem. Let me know if you still have problems.

compiled with -O0. Included are patches that should fix the problem
(of course I have confirmed -O2 works with this patch).

BTW, here is a platforms/regression test failure(serious one--backend
death) matrix.

Here are patches for bin/createdb/createdb.sh.

structs from libpq-fe.h, as we previously discussed.

There turned out to be sloppy coding practices in more places than
I had realized :-(, but all in all I think it was a well-worth-while
exercise.

I ended up adding several routines to libpq's API in order to respond
to application requirements that were exposed by this work.  I owe the
docs crew updates for libpq.sgml to describe these changes.  I'm way too
tired to work on the docs tonight, however.

This is the last major change I intend to submit for 6.4.  I do want
to see if I can make libpgtcl work with Tcl 8.0 before we go final,
but hopefully that will be a minor bug fix.

 They were missing a "PG_" prefix so were not substituted properly.
