Hmm. I'll take a look, but I'm not terribly hopeful. I have looked
briefly at what Bash does for filename completion, and as I recall
it was massive, spaghetti-ish, and way too much in bed with various
implementation details of libreadline --- they don't pretend to work
with libedit. I'm not prepared to go there. It's reasonable for Bash
to expend huge effort on filename completion, because that's such a core
use-case for them, but I don't think it deserves as much work in psql.

I think the point is that before rl_filename_completion_function the
function existed but was just called filename_completion_function.
It's possible that that's obsolete --- I've not really checked.
