Well, that depends on what you mean by "database." In many other products
each database is completely separate (with it's own cache, processes etc).
In PostgreSQL, there's a cluster of databases, and all of them share the
same cache (shared buffers) etc.
I don't think you'll get performance improvement from running two
PostgreSQL clusters (one for DB1, one for DB2). And when running two
databases within the same cluster, there's no measurable performance
So the two options are exactly the same.
