postgres calls schemas. The best way to do what you want might be
to translate your mysql DBs into schemas, and then "set search_path"
would be a good approximation to "use".
The issue here may be data isolation. Suppose you have two independent groups, one with database A and one with database B. (Think of a company that hosts databases for its customers, for example.)
In the ideal situation, the people with access only to database A should not even be able to learn that database B exists, much less access it in any fashion.
I believe PG does not have the capability to completely isolate other databases from users running on the same server, I'm not sure if MySQL does or not.
However, if there are any times when it might be necessary to query both database A and database B, then schemas are the way to go.
