Re: DB alias ?

Then someone who wants to look at old JAN data will have the same problem :-(

If I recall, Oracle enables something like this. Multiple tnsfilenames (or something like that). There was a connect layer on the server side that the DBA had access to where you could do stuff like this.

Actually, read the DBA's mind.

How about...

postgres=# create db_alias FEB to db JAN;
postgres=# drop db_alias FEB;

The DB name used in the connect is picked up from the current date/time. But January is oevr and I don't want to create the FEB DB until Feb 15th. In the meantime, I want those who try to connect to FEB to connect to JAN (for example).
