Preliminary code review for domain CHECK constraints patch: add documentation,
make VALUE a non-reserved word again, use less invasive method of passing ConstraintTestValue into transformExpr, fix problems with nested constraint testing, do correct thing with NULL result from a constraint expression, remove memory leak. Domain checks still need much more work if we are going to allow ALTER DOMAIN, however.
