No, you can't turn it off, and yes, many people do notice that it's not
the way some other databases work. (Some database make this configurable).

You can use ~*, you can also index on function results (eg, you can create
an index on a function. So, you could

  create unique index yourtable_pkey on yourtable ( upper(pkeyfield));

which would only allow one 'Joel', regardless of how you cap me.
