You almost certainly want to go for schemas, at least from a performance point of view. The overhead of a schema is small (basically one more row in pg_namespace) whereas the overhead of a database is not trivial. The main reason you might not want to use schemas is if you want fairly airtight separation between different services. Separate databases would prevent services from looking at each others' catalog entries. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
