If you mean installed on the OS, it's impossible from the SQL command
line. If you mean installed on your database, it's difficult to know.
You need to check if a specific function / type / operator / whatever
that this extension provides is available. It's difficult and error
prone.
That's why we now have the extensions system. Now as "in 9.1".

Yes. That's because extensions are a new PostgreSQL object since the 9.1
release.
