Ok, makes sense.

What's the advantage of that, compared to normal REINDEX?

I think it would work if you dropped and recreated the constraint in a
single transaction. The DROP would acquire an exclusive lock on the
table, so anyone trying to insert to it would block.

Finnish texts do tend to more longer than English. It's not a problem in
most places, but for example "Rename" in the favourites manager is
translated to "NimeƤ uudelleen", which is quite a bit longer. If we just
made the space reserved for the button bigger, it would look quite silly
in English I think. But as it is, the button is partly underneath the
"Remove" button.

Yeah, probably don't want to change it now. I'd suggest changing them
all to the true/false statement form in the future.

Only somewhat ;-). I hacked wxXml, wxrc and stringextract to do that.
I'll clean that up and post patches to wx the wxWidgets list, as well
the changes to stringextract.

Meanwhile, anyone interested in the pgadmin3.pot file I have here with
the file/line numbers in it? I can post it if so..

There's a bunch of unused space. I can send you a screenshot.

Yeah, probably better to leave it until next release.
