07c33ba79e 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.
