Aside from the numerous serious problems pointed out in the
documentation, this has an even more fatal objection, which is that it's
unspecified what the result value is and thus there is no portable way
of *using* the result after you have it. (If the PG driver returns an
OID you certainly couldn't use that the same way as some other driver
that returns a primary key ... especially a multicolumn primary key ...)
This "portable" function is so unportable that I see no reason to
accept it as precedent.
