Change connection (IP, or Databasename)

hi,
I am using Access as a front-end for postgresql via ODBC.

The postgresql-server is hosted on a separate linux-computer.

I like to change the database on the SQL-server for developing or
change the IP of the connected SQL-server so that the original data wouldn�t
be changed.

Does anybody know a quick and comfortable way to do this. I know the
possibility of importing the whole tables once again but they all have a
header like "public_" which I have than manually to change.
