Tom Lane 07c33ba79e pg_dump -d or -D didn't quote special characters in INSERT data
correctly.  -D had problems with tables with inherited fields, also.

Jan Wieck 566c712c58 Revert some changes from the INTERSECT/EXPECT patch that broke
rule system semantics by having Var nodes referenced across multiple
parsetrees when rules split them.

Added more tests to the rules regression test.

The code in question resulted from v6.3 based development and was
a little careless applied to the v6.5 source tree.

Jan Wieck 28fc5d7b83 Reenabled parentheses for grouping multiple rule actions and
added this syntax to rules regression test so it will show up
if someone breaks it again.

Jan Wieck ef590e101e Changed ExecConstraints() and ExecRelCheck() to cache the constraints
qualification expression trees in the execution state. Prevents from
memory exhaustion on INSERT, UPDATE or COPY to tables that have CHECK
constraints. Speedup against the variant using freeObject() is more than
factor 2.

Tom Lane 48fd9a2cc2 Add equality checking for T_Query so that we don't get
complaints in UNION regress test.  Probably still need some more node
types to be handled here, but I'm done for the day...

Bruce Momjian 3982368a4e The libpq function PQfnumber does not handle case-insensitive
comparisons correctly. The psql monitor converts all table and field
names to lower case. If the PQfnumber function is called with a mixed
case name, it will always return -1.

Tom Lane 724119a979 Modify int8 to not depend on sscanf(), and fix configure's test
for int8 support.  configure now checks only snprintf() for int8 support,
not sprintf and sscanf as it used to.  The reason for doing this is that
if we are supplying our own snprintf code (which does handle long long int),
we now only need working long long support in the compiler not in the
platform's C library.  I have verified that int8 now passes regression test
on HPUX 9, and I think it should work on SunOS 4.1.* and other older
platforms if gcc is used.
