pgadmin 1.4 + pgsql 8.1.0

Hi,

Pgadmin is amazing.  You can log on with a user account that's been 
authenticated through Linux PAM and then run a command like pg_dump or 
createdb that you wouldn't have access to run on the linux command line as 
long as postgres approves that access.   Is there a way to bring that power 
to the command line?   If I log into a server as a certain user who doesn't 
have the access that the postgres user has, can I  use or access postres 
someway to check that a superuser has given that access in postrres and if 
it has wrap around the postgres user account (like what happens with 
pgadmin) and execute the command like createdb?

Is there a web based version of pgadmin?  Is the source available for 
pgadmin?

Thanks,
