I am not sure about a SQL Query.
But if you login to the database using the command line psql interface and run
\l
it will give you output similar to this:
intsys=> \l
List of databases
Name | Owner | Encoding
-----------+----------+-----------
intsys | intsys | SQL_ASCII
template0 | postgres | SQL_ASCII
template1 | postgres | SQL_ASCII
(3 rows)
intsys=>
Not sure if this will help you.

Such information is in the system catalogs: http://www.postgresql.org/docs/7.4/static/catalogs.html If you run psql with the -E option, you can see the queries that psql makes when you issue commands like \l to show the list of databases and their owners. You can then copy those queries and modify them to meet your needs. The name of the current user is available as CURRENT_USER and SESSION_USER -- see the Miscellaneous Functions documentation for the difference: http://www.postgresql.org/docs/7.4/static/functions-misc.html -- Michael Fuhr http://www.fuhr.org/~mfuhr/

select datname, usename
from pg_catalog.pg_database, pg_catalog.pg_user
where datdba = usesysid and usename = current_user;
