Hm.  You're right that pgAdmin could be smarter than plain psql, since
it allows nonsequential typing of a command.  Whether this would be worth
pgAdmin having its own implementation of tab completion is something you'd
have to take up on the pgAdmin lists.

The big picture there is that psql's tab completion doesn't contain a full
blown parser but just looks at a couple of words of preceding context.
To be able to do anything with a nontrivial FROM clause would seem to
require adding a whole heck of a lot of machinery.  If you're sufficiently
excited about it to work on the project, feel free.  I've thought for some
time that tab-complete.c is overdue for being thrown away and rewritten
from scratch; but it would be a *lot* of work to make it significantly
better, and I doubt anybody is thinking about doing that.
