Except someone did make a very good point that as soon as we add some feature that Oracle doesn't have, they can turn around and add the same feature using a different syntax, and then we'd have a real mess. If we're going to be serious about easing migration from Oracle we should really be adding PL/SQL as a language, because there's already some pretty non-trivial differences (off the top of my head, how you handle sending debug info back is a big one, as is our lack of packages). IMO, if the community is going to concentrate on a migration path, I think MySQL is a much better target: - There's already a commercial solution for migrating from Oracle, and there's probably more money there than in migrating from MySQL - Enabling migration from MySQL would be a tremendous benefit to the growth of the community, because there's a lot more people who would try that on a whim and stick with PostgreSQL than for any of the commercial RDBMSes - Having some kind of compatability mode would make it much easier on all the OSS projects that currently only support MySQL to add PostgreSQL support. It also makes it much easier for people to use PostgreSQL over MySQL -- Jim C.
