Something I was pondering the other day was whether a pg_compat_chk utility would be practical/desirable. You run it against your existing database / schema dump and it prints a set of warnings: Old version = 7.2.1 New version = 7.4.0 Warning: schema support introduced (v7.3) all objects will be placed in the default schema Failure: DEFAULT 'now' not supported (v7.4) table1.column2 table2.column3 Notice: timestamp now holds milliseconds by default (v7.3) tableX.whatever My main concern would be that a 90% solution might be worse than nothing at all. Incidentally, this is not idle speculation, but something I might well have time to stick in gborg during the 7.5 devt cycle. -- Richard Huxton Archonet Ltd ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
