Ok, here's a quick example I whipped up and if you run it it clearly
shows it's using the comparison function from the operator class.

It basically replicates the entire infrastructure for the text type as
a new type, "text2" so there's planty of scope for confusion, but
postgresql correctly picks the right function.

Have a nice day,
