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

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.

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.

Add equality checking for T_Query so that we don't get

complaints in UNION regress test. Probably still need some more node
