I think the question is: do you have queries that retrieve data from different schemas in Oracle?
If so then the only way to go in PostgreSQL is to use multiple schemas.
If you don't need cross-schema/database queries then I don't think there is none of the solution is particular better
thanthe other. Both have advantages and disadvantages (as described by the other posters)
