Thread: pgsql: Let ALTER TABLE Phase 2 routines manage the relation pointer
Let ALTER TABLE Phase 2 routines manage the relation pointer Struct AlteredRelationInfo gains a new Relation member, to be used only by Phase 2 (ATRewriteCatalogs); this allows ATExecCmd() subroutines open and close the relation internally. A future commit will use this facility to implement an ALTER TABLE subcommand that closes and reopens the relation across transaction boundaries. (It is possible to keep the relation open past phase 2 to be used by phase 3 instead of having to reopen it that point, but there are some minor complications with that; it's not clear that there is much to be won from doing that, though.)
