In that case, I suggest the attached, even more simplified patch. It
assumes that the quote character stored in $lp in the existing version
is always "'" (a safe assumption for DBD:Pg, I think, in a way it wasn't
for DBI, from whence the code for the LITERAL_PREFIX and LITERAL_SUFFIX
was copied into DBD::Pg), and therefore performs the escaping of the
three agreed-upon characters for all non-numeric data types.

If you agree that this tack makes sense, I'll submit the patch to Edmund
Mergl.

Daviid
