Nah, that's not really relevant. The speed concerns I have here
are mostly independent of whether the SQL function is written
in string or SQL-standard form. Also, I think all of those
contrib functions that are at all performance-relevant are
capable of being inlined, and so wouldn't reach this code anyway.
