Hi, and thanks for your input,

This is probably why I was so frustrated - I thought that there should be an equivalent in PostgreSQL.

I want to index on a REGEXP_REPLACE() - I thought using lower -> upper would be a good test. I could always have used another REGEXP_REPLACE() for my testing, but I then became "obsessed" with the idea of using REGEXP_REPLACE() as a substitute for UPPER() - kind of an obfuscated code competition with myself! :-) Again, thanks for your input.
