Yes. The auto-completion functionality does not behave as expected on
linux with GTK. That's why we disabled editing combo-box on GTK only. I
know that disabling it makes our lives harder. But enabling it just
makes it worse.

Probably. wxWidgets is a toolkit that allows us to make pgAdmin
available on many platforms. But of course, when a widget is not
available in one platform, it creates it from scratch, which may result
in different behaviours. We try to avoid them as possible, and maybe
sometime we don't use wxWidgets in the best possible way, but I'm sure
you can find differences between platforms.

Oh, yes, I agree. Would be stupid if I didn't. All I can tell you is go
see the wxWidgets guys and tell them to release a fix for that in 2.8.
Good luck with that.

On the details, if we enable the editable field in the combobox, when
you'll written some of the type for your column, it will try to
autocomplete it. But its way to autocomplete it will make it select
another part of the type which you'll erase while typing further, making
your whole typing session a complete mess.

If there was someone like that (and with time to do it), it would
already be fixed.

BTW, going to wxWidgets 2.9 will probably solve the issue. But, AFAIUI,
we are not really near having complete 2.9 support. Moreover, I don't
know one Linux distribution that offers wxWidgets 2.9.

Something probably easier to do is to allow typing while disabling the
autocomplete feature. I'm not sure at all it's doable, but we should
try. Anyone who has the time to work on it, go ahead :)

I know that. And I'm sorry. But right now, I don't know how to do best.
