But I don't immediately see anything too worrisome. I take that back :( It looks like the type input function may be a problem, because it doesn't look like it knows what the collation is yet. In other words, PG_GET_COLLATION() is zero for the type input function. But I need to do a comparison to find out if the range is valid or not. For instance: '[a, Z)'::textrange is valid in "en_US" but not "C". The range constructor: range('a', 'Z') is fine though. Not sure what to do here. Regards,Jeff Davis
