Re: BUG #1996: DISTINCT fails with national character varying

Thanks, Tom!

I'll tackle this issue this weekend.
I'll also upgrade to PostgreSQL 8 (most probably)

Thanks once again for your comprehensive reply!

Best regards,
Ludmil Tinkov

This has been seen to happen when you select a database encoding that
does not match the encoding expected by the postmaster's LC_CTYPE locale
setting. It's really a bug in the locale definitions, if you ask me,
but good luck getting the glibc guys to change those :-(. In the
meantime, make sure your locale and encoding agree.
