OK, DROP COLUMN now seems to work perfectly. All the old test cases that failed now work fine.
However, I'm not happy with the way dropped columns are renamed. I want to give them a name that no-one would ever want to use as a legit column name. I don't like this behaviour: test=# create table test (a int4, b int4); CREATE TABLE test=# alter table test drop a; ALTER TABLE test=# select dropped_1 from test; ERROR: Attribute "dropped_1" not found test=# alter table test add dropped_1 int4; ERROR: ALTER TABLE: column name "dropped_1" already exists in table "test" It's a bit confusing, hey? What should we do about it? Maybe I could make ADD COLUMN give this message instead for dropped columns? ERROR: ALTER TABLE: column name "dropped_1" is a dropped column in table "test" ... or something ... We could name the fields "________dropped_x" sort of thing perhaps????
