Hi! *Waves*
First off, it all seems to work as described:
- regressions pass
- domains work
- tried various inherit options (merging constraints, alter table no
inherit etc)
- pg_dump/restore
I didn't care for the changes to gram.y so I reworked it a bit so we
now pass is_only to AddRelationNewConstraint() (like we do with
is_local). Seemed simpler but maybe I missed something. Comments?
I also moved the is_only check in AtAddCheckConstraint() to before we
grab and loop through any children. Seemed a bit wasteful to loop
through the new constraints just to set a flag so that we could bail
out while looping through the children.
You also forgot to bump Natts_pg_constraint.
PFA the above changes as well as being "rebased" against master.
