We added pg_constraint rows for all not-null constraints, first for tables and later for domains; but while the ones for tables were reverted, the ones for domains were not. However, we did accidentally revert ruleutils.c support for the ones on domains in 6f8bb7c1e961, which breaks running pg_get_constraintdef() on them. Put that back. This is only needed in branch 17, because we've reinstated this code in branch master with commit 14e87ffa5c54. Add some new tests in both branches. I couldn't find anything else that needs de-reverting.
