No. A function is an autonomous transaction. You can use savepoints.

This question comes up very often.  Would somebody please write it and a
detailed answer to add to the FAQ in the Wiki?

Of course its already in the documentation - not sure if the posters
of this question in the mail already read the documentation, the faq
