Just FYI, that's a known problem with the regex operators if you're
using UTF8 database encoding (or more generally, any multibyte encoding,
but UTF8 is usually the one people complain about). I don't believe
updating to 8.4 would have fixed it for you --- maybe the reason the
problem went away is you switched to a different encoding, such as one
of the LATINn family?
There is a tentative fix in 9.0, FWIW.
