Hi all,
I've been doing some more research on this:
pg_dump -s works as expected
pg_dump -a works as expected
pg_dump -v shows that pg_dump crashes when dumping user defined functions.

There's a lot (~30) plpsql functions how could it be a problem.

I'm also surprised that pg_dump -s dumps those function without crashing.
