PgAdmin Portable is the PgAdmin whatever it is packaged with a PortableApps.com launcher as a portable app, so you can manage PostgreSQL 7.3 and above running on any platform, as well as commercial and derived versions of PostgreSQL such as Postgres Plus Advanced Server and Greenplum database on your iPod, USB flash drive, portable hard drive, etc. It has all the same features as PgAdmin, plus, it leaves no personal information behind on the machine you run it on, so you can take it with you wherever you go.
Great portable version of the PgAdmin application. I use it extensively to control my PostgreSQL Portable instance - and it works great!!
