I take that back: you can find it out if you really want to. You can
get your own function OID from the fcinfo->flinfo struct, look that up
in pg_proc, and get the pronamespace field. If you want the schema
name, and not just its OID, that'll cost you a second cache lookup.
Not too many lines of code, though it might be wise to fix things so you
need not repeat this each time through the function.
