Hi, is there any noticeable difference between a cluster with many
databases and a database with many schemas?
I've got a quite huge database on Oracle with about 400 logically
disjoint schemas. I could import that into PostgreSQL as many
different databases, or as one database with many schemas.
From the application point of view it could be easier to have
different databases, as for now the applications log in into
different schemas, so this behavior wouldn't change.
Do you see any drawbacks of any of the solutions?
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 than the other. Both have advantages
and disadvantages (as described by the other posters)
Regards
Thomas
