You'll need to provide some actual details if you want useful comments.
Let's see the table schemas, the view definitions, and the EXPLAIN plan
(I'll spare you a request for EXPLAIN ANALYZE given that it'd take 24
hours to get ;-) ... although some estimate of the number of rows
expected would be helpful).  And I trust they remembered to ANALYZE the
underlying tables first?  Also, which PG version exactly?
