1) I downloaded PokerTarcker 3 and to connect I have to enter PostrgreSQL login and password, is that the same as in elephant, and where can I find it. The login and password I tryed don't work.

2) I downloaded some databases from NL10, but now Im playing NL25 so I dont need this huge database (5GB in postGRE) how can I delete it and dont delete my NL25 database
