When you specify "server1" or "server2", the PSQL engine is looking for a database name not a server name.
It's not possible to select from one server and insert into another server through ODBC through the PCC.
If you need to insert all the records from table1 (no WHERE restriction) you can do it from DOS prompt:
butil -copy btrv://server2/databasename?table=table1 btrv://server1/databasename?table=table1
