Over time, I mistakenly did something like this: CREATE TABLE a (); CREATE TABLE b () INHERITS(a); ALTER TABLE b ADD col int; ALTER TABLE a ADD col int; where I should have left out the third statement. Not a great loss, the only consequence I've observed being pg_attribute.attislocal = true, so dropping a.col will not drop b.col. Is there a DDL way to change that, short of dropping the column from both tables and re-adding it to the parent alone? If not, what's the danger of updating attislocal directly? If it makes any difference, I don't actually plan to drop the column anytime soon.
