Although postgres itself doesn't seem to have a thing such as Informix' "synonym" which allows more-or-less transparent access to a table in a remote database, there is a utility in contrib directory of the postgres source called dblink, which allows access to different instance of postgres by opening connections. I have only played with it for testing and have no idea of its limitations, but it might serve your needs.
Greg Williamson DBA GlobeXplorer LLC -----Original Message----- From: Garth Thompson [mailto:[EMAIL PROTECTED] Sent: Wednesday, June 30, 2004 3:54 PM To: [EMAIL PROTECTED] Subject: [SQL] Queries across multiple database I am in the process of migrating the databases for an application from mysql to postgres. The application is uses several different databases. From what I have read, postgres still does not support queries across multiple databases. If this is still true, does anyone have any tricks to get around this? I'm sure this is a common problem for people migrating from mysql. The obvious answer is to just migrate everything into one larger postgres database, but I would like to avoid this if possible - many a line of could would need to be touched if this was done.
