Thread: Switching database inside current connection
I have to search multiple, identical databases on a server and am currently having to create a DataSource for each database on the server and then get a connection. How would I create a DataSource for the server and then modify the connnection to "switch" databases. I would like to just re-use the same connection for obvious reasons. I'm running server version 7.3 and the coinciding JDBC driver version. Jeff

This is not possible with postgresql. You can only use the database you initially connected to. To access parts of other database you can use contrib/dblink, but for your purposes I think multiple connections are required. Kris Jurka

If you can move away from individual databases to multiple schemas in one database, then your problem would be solved. Schema support was initially added in 7.3, but the tools needed for examining schemas and such were not quite done all the way back then. Upgrading to 7.4 at least makes dealing with schemas a little easier, and if you're upgrading to 7.4, might as well go all the way and get 8.1.4. 7.3 is on the very tail end of what's considered "supported".
