Indeed, this is a FATAL_ERROR. From two threads I got:

// Thread #1
FATAL_ERROR: ERROR:  source database "template1" is being accessed
by
other users
DETAIL:  There is 1 other session using the database.

// Thread #2
FATAL_ERROR: ERROR:  source database "template1" is being accessed

DETAIL:  There is 1 other session using the database.

I would try using dbname=postgres.  

aaaaand.... it works. Two databases have been created with return
status "COMMAND_OK".

If you get the same error, I would say your server is in single user
mode?
