The main problem I see with case-insensitivity is the fact that there are always more than one way to do it, as it depends on charset _and_ locale ;( For example 'Ä'=='ä' in my locale but not in US, not to mention that in some locales even the character count may change when going from upper to lower case. So I suspect that only valid reason for case-insensitivity is compatibility with arbitraryly-case-altering OS-es, like the ones Microsoft produces. For any other use WYSIWYG field names should be preferred. > Are there any real reason why postgre is sensitive about field names (except > SQL92 states that this is how it must be)? > > I suppose somewhere along the way I have all field names separated from the > query, and in which file(s) does that happen?

I guess the best place would be sobewhere very near lexer. You could also try just uppercasing anything outside ''/"" even before it is passed to backend. --------- Hannu
