Yeah, now that we allow recursion in SQL functions, you don't need a PL
language to overflow the stack.  So that particular argument is seeming
a bit weak.  Were there any other security arguments against making
plpgsql standard?

Inability to load existing pg_dump archives might be a bigger objection.
However, we could fix that if pg_restore were modified to not stop dead
in its tracks upon encountering an error.  IMHO that was a wrong choice
from the beginning ... pg_dump scripts don't act that way, and
pg_restore should not either.
