Oh... Duh!!! Geesh... for some reason I figured it would call the
"built-in" UPPER, but obviously it won't. ha ha ha. *sigh*
My next question then is how to get around this? I could just rename my
function but it's nice to leave it UPPER since that is what it does. Is
there another function that will uppercase? Or is there some way to
call the other UPPER function? Or something within plpgsql I don't know
about.
Thanks!
