How is that relevant? It's still parseable with parameter placeholders in
place of literal parameters.

Presumably \beginliteral \endliteral would be psql's way of specifying
parameters to ship over as parameters.

It probably is, but that's not what I was thinking of. I was thinking it
wouldn't have to poke around inside the string at all, it would pass it as an
out-of-band parameter using the new FE protocol.
This helps with DBI too, since you can already do that.
$dbh->do("CREATE FUNCTION foo as ? LANGUAGE SQL", $func);
Is a whole lot cleaner for the front-end to do than trying to quote the
parameters and interpolate them into a query.
