When the casts removal was > mentioned in pg-devel, who was there asking about backwards compat? If you need 100% backwards compatibility, you keep using 8.2 (or whichever). That's why we keep maintaining back branches for so long. If we were to try to keep 100% compatibility in new releases, our ability to add new features would be crippled. So I'm not about to apologize for the fact that 8.3 exposed the brokenness of some broken apps. Anyway, Devrim is quite right that mere installation of an RPM cannot execute any sort of database conversion. The functionality would need to be invoked sometime else. That doesn't mean it has to be manual though. Could we put it in the start script, invoked by something like "service postgresql upgrade"? Exactly what does a conversion look like in Debian's packaging, anyway? regards, tom lane -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
