oups. just thumbled over this as well when i forgot a FROM in a WHERE ... IN
(....) and damaged quite some data. the bad query went like this:

SELECT * FROM movies.names WHERE mov_id IN (SELECT DISTINCT mov_id WHERE
mov_name like '%, %' LIMIT 2)

the subselect is missing a FROM <table>. in that case, pgsql seemed to also
ignore the LIMIT 2 and returned 3706 records out of ~130000... no clue which
ones :-/
