Postgres logo, copyrights, etc...

Hi all,

I'd like to know if there is any 'postgresql-powered' (or sg. like that)
logo available on the net. I have checked a few ftp and web sites and
been searching for it but without success. (I just want to use it on a
website which is 'postgres-powered' really!)

My other problem/question is about copyrights. I developed a
registry-system for universities using Java, JDBC, Postgres and Linux
and I planning to sell it but before I do anything I'd like to know if
it's legal... I'd give these "helper-tools" along with my system (and
with source) and I'd only charge for what I did, however I know that
this program depends on all of the above.

Please, someone tell me if it's OK or not.

Thanks in advance,
Peter Blazso
