replacing MS Access - experiences?

[Dr. Michael J. Chudobiak]

We use MS Access extensively as a front-end to our Postgresql databases. 
Has anyone successfully replaced MS Access with a Linux tool, for 
simple-to-moderately-complex queries and reports? I'd like something 
that a secretary can use, not a database designer or coder.

I know Rekall is out there, but I've never had good luck with it 
(crashes when designing queries, can't compile, non-obvious GUI, 
strangely structured web site, generally bad karma, etc).

PgAdmin is -great- for administering psql - I guess I need the 
PgSecretary package :-)
