I am attempting to drop a database from PgAdmin 3 and that i understand this error message:

ERROR: can't delete current database
SQL state: 55006

how do i pressure the remove/fix this error, of the database?

Fast solution in PgAdmin: just create another empty database. Choose it. Remove the first. Voila.

You may also connect with the command line without choosing a particular database, and drop your database.

The issue here isn't that other customers are attached to the database, but that you are.

Rather than creating new database he is able to simply connect with postgres database, that is produced automatically in most new PostgreSQL installations. And even when it's not there - template1 ought to be ever present.
