My bad--gave you the wrong url.
http://git.postgresql.org/gitweb?p=pg_top.git;a=summary has the project
I meant to point you toward.

I understand what you want.  The reason you're not getting any
suggestions is because that just isn't exposed in PostgreSQL yet.
Clients ask for queries to be run, eventually they get rows of results
back, but there's no notion of how many they're going to get in advance
or how far along they are in executing the query's execution plan.
There's a couple of academic projects that have started exposing more of
the query internals, but I'm not aware of anyone who's even started
moving in the direction of what you'd need to produce a progress bar.
