Well, you'd really want to change all the comparison operators because
otherwise I think indexes would be screwy and I don't know off hand if
this will cause problems, but I can imagine that it might, if only on
queries from clients and such on the system catalogs.
One other option is to find or make a case insensitive collating locale
for your operating system and use that when initializing the database.
I've never tried so I can't say whether that'll have its own problems.
