Обсуждение: pgsql: Add check for matching column collations in ALTER TABLE ... INHE

Add check for matching column collations in ALTER TABLE ... INHERIT.

The other DDL operations that create an inheritance relationship were
checking for collation match already, but this one got missed.

Also fix comments that failed to mention collation checks.
