Vacuum doesn't vacuum functions (AFAIK). It does, however, use the type
information about columns of tables that it's vacuuming --- at least it
does in vacuum analyze mode, not sure about plain vacuum. That's why
I'm suspicious that you have somewhere a forgotten table that has a
column of circle type...
