I've been working on trying to normalize a table that's got a bunch of text fields. Normalizing the first 4 has been a non-issue. But when I try and normalize 2 additional fields a bunch of query plans go belly-up.

Try increasing join_collapse_limit/from_collapse_limit.  I'm a bit

relations in the subqueries.

Hell, never thought about that. Bumping it up did the trick. Thanks!
