To me, as long as they go back into the database via SPI, anything they
can get to from there is OK.  What I meant to highlight upthread is that
we don't want trusted functions being able to access other functions
"directly" without going through SQL.  As an example, a PL that has FFI
capability sufficient to allow direct access to heap_insert() would
have to be considered untrusted.
