You would really, really, really be better off fixing your application
to double-quote as needed. Otherwise you're locking yourself into an
entirely nonstandard variant of SQL.

Well, it's not exactly hard to lobotomize downcase_truncate_identifier,
or maybe better s/downcase_truncate_identifier/truncate_identifier/g in
parser/scan.l. The problem is dealing with all the ensuing breakage.
The first thing I imagine you'd hit is that there's general lack of
consistency among applications as to whether the names of built-in
functions are spelled in upper or lower case; this is partly because
many of those names are actually keywords according to the standard.
