Wouldn't it be possible to create a variant of regexp_replace, i.e.
regexp_replace(citext,citext,text), which would again lower-case the

regexp_replace(text,text,text)?
Sure, but then you end up with this:
template1=# select regexp_replace( 'Fxx'::citext, 'X'::citext, 'o');
regexp_replace
----------------
foo
(1 row)
Which is just wrong. I'm going to look at the regex C functions today
and see if there's an easy way to just always pass them the 'i' flag,
which would do the trick. That still won't help replace(),
split_part(), or translate(), however.
Best,
