I was thinking the same thing while reading the patch.  But please,
make str_toupper() and friends declare their argument "const" if you're
going to do this.

Another issue in this area is that these functions could do with some
refactoring to eliminate useless text/cstring conversions; I'm pretty
sure some code paths are doing cstring->text->cstring in direct
succession.  Also, it seems a bit inconsistent to be relying on
oracle_compat.c for upper/lower but not initcap.
