pgsql: Fix oversight in ALTER TYPE: typmodin/typmodout must propagate t - Mailing list pgsql-committers

Fix oversight in ALTER TYPE: typmodin/typmodout must propagate to arrays.

If a base type supports typmods, its array type does too, with the
same interpretation.  Hence changes in pg_type.typmodin/typmodout
must be propagated to the array type.

While here, improve AlterTypeRecurse to not recurse to domains if
there is nothing we'd need to change.

Oversight in fe30e7ebf.  Back-patch to v13 where that came in.
