Hi! It is generally not advisable to write to system catalogs directly ... However, I have a database with dozens of schemas and hundreds of tables. There is a bunch of useless comments on columns I want to get rid of, scattered all across the db. The fastest & easiest way would be: DELETE FROM pg_description WHERE description = 'My very special totally useless comment.'; AFAICS, there are no side-effects. Are there any? TIA!
