Re: Regular expression for lower case to upper case.

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

I was going mad trying all of these from my searches.

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.
