SUPER! (Thanks to both Joe and Jochem who took the time to
answer)

Now, with both schema and prepared queries (stored procedures)
support there is NOTHING LEFT of the Oracle functionality I used
to miss in 7.2 (except perhaps tablespaces). Shema support is
essential for logical grouping of tables and mapping to applications
which, in extension, enhances reusability a great deal! (userB who
owns schemaB and represents application B can now re-use
schemaA.table1 without having to connect as userA & do the
joining on the client side, provided of course that userB has been
granted read rights on schemaA.table1) When I was working with
Oracle, we had a 1:1 mapping between schema<->user/owner<-
>application - this can now be reproduced in Pg as well!

Kudos to the dev team, you have done a tremendous job!
