Not familiar with Oracle's solution, but ...
Without knowing the details, it's difficult to be sure if PostgreSQL's
native security meets your needs. You can assign read/write/create
permissions to databases, schemas, tables, and other objects:
http://www.postgresql.org/docs/8.2/static/sql-grant.html
This falls short if you need permissions at the row or column level,
which PG doesn't support naively (unless this has been added in 8.3
and I simply haven't see the announcement).
For that, the best approach I know for you is Veil:
