hi.

rearrange the patch.
v3-0001 and v3-0002 is preparare patches.
v3-0001 add function: ExecPrepareExprSafe and ExecInitExprSafe.
v3-0002 add function: DomainHaveVolatileConstraints


v3-0003 tests and apply fast default for domain with constraints.
v3-0003 table with empty rows aligned with master behavior.
also no table rewrite if the domain has volatile check constraints,
so less surprising behavior.
