We're near the end of migrating our 100 databases from Sybase to PostgreSQL, so I might be able to give you some hints. To know where to even start, I'd have to know more about your software environment; the conversion itself is not all that hard, but getting the same version of the software to run against both products was a little tricky, even using a framework designed with portability as a very high priority. (If you just scatter the SQL code around your applications in string literals, you're going to have a very hard time of it.) For a while we actually ran our web site with the renderers doing load balancing between Sybase and PostgreSQL databases. The exact same code was used for both except for a portability layer of a few hundred lines of code for each product and (of course) the JDBC drivers. So yes, it is *possible*. -Kevin ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
