I managed to drop a table without apparently droppig it's primary key After recreating the table I try to recreate the primary key. If I run the following: ALTER TABLE case_histories ADD CONSTRAINT case_histories_pkey PRIMARY KEY(case_history_id); Postgresql responds with: NOTICE: ALTER TABLE / ADD PRIMARY KEY will create implicit index "case_histories_pkey" for table "case_histories" ERROR: relation "case_histories_pkey" already exists SQL state: 42P07 The table does not have this key. Assuming that the response is correct, where can I find and/or delete this relation? I have deleted an entry inpg_constraint with that name but that did not do the trick TIA Joost Joost ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
