If I create an index based on a function, as:
create index fubar on table (function(field));
and then I later:
drop function function(...);
It makes it impossible to pg_dump a database until one also explicitly drops
the index. This happens in 7.0 and I haven't checked it 7.1.
If it were my code, I wouldn't call it a bug, I'd call it user error, but there
should, at least, be some mention of this in the FAQ or something.
