Not in the stock installation but you can establish a connection between one PostgreSQL server and another with contrib/dblink, or with just about any other data source using David Fetter's dbi-link. http://pgfoundry.org/projects/dbi-link/ PostgreSQL has several server-side languages such as PL/Perl, PL/Python, PL/Tcl, PL/Ruby, PL/php, PL/Java, PL/R, etc. In general a server-side function written in one of those languages can do anything a standalone application could do, such as connecting to another database, even a different DBMS (you could connect from PostgreSQL to MySQL, Oracle, SQL Server, etc.). -- Michael Fuhr ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
