I think we could tweak the test harnesses to run all the tests with different segment sizes. That would get pretty good coverage. More generally, the methodology that we should not add an option unless we also change the default because the option would otherwise not get enough testing is a bit dubious. > and I doubt that most tool writers would be quick to > add support for a feature that very few people (if any) use. I'm not one of those tool writers, although I have written my share of DBA scripts over the years, but I wonder why those tools would really care. They are handed files with predetermined names to archive, and for restore files with predetermined names are requested back from them. What else do they need? If something is missing that requires them to parse file names, then maybe that should be added. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
