Strange. The string '.CH' should match any single character directly
followed by 'CH'. It *should* match '_CH' as well as ' CH'.
If you want the "." to match something, then use the appropriate list
[a-zA-Z] for alphabetical characters and suchwhat. If you want to match
the "." character, then use '\.CH'.
Question: why aren't you using ~* (which does a case insensitive match)
rather than upper(xy) ~ '.CH'? I haven't done benchmarking so I don't
know which is faster...
I hope this helps.
