Hiding extraneous stuff in pgAdmin3

When starting out in Postgres 9 using the bundled pgAdmin3 app, I was confused by all the various pieces of the installation. Postgres has many internal support files, tables, and such, none of which is useful to a newbie like me.

Thanks to SeaPug, I got a tip to hide all that extra stuff, instead showing just my own tables, etc.

1. In Preferences, choose the Browser tab, and uncheck "Show System Objects". 
2. Restart pgAdmin3.
