Oh well, you are indeed right, I went through the whole view hierarchy
and replaced all volatile function calls (I used to use a trick
defining a function to avoid a join that used to perform better in
earlier versions) with explicit JOINs, also I relabeled some functions
that were indeed STABLE and now everything is working fine. I was
amazed that some of those views predates Postgres support of JOINs, I
guees we have been using Postgres for a very long time :-).

Just out of curiosity, why the change?
