If you're talking about multiple databases served by a single
postmaster, I don't believe it's much of an issue.  You might start to
notice performance problems when you got past a few thousands, but
that'd have more to do with kernel performance (slow lookup for many
files in one directory) than Postgres itself.

Concurrent connections is a much more interesting question, but no one
can give you any interesting answers without a lot more assumptions
than "typical Linux server".  How much iron is that really, and what
are your concurrent users going to be doing?
