This makes the patch larger for no good reason and tends to If you want to remove changes like this using: "git checkout -p HEAD" is very useful if youre using git. It allows you to selectively revert hunks of not-checked-in changes...

I agree. While not every feature needs regression tests, something this complex certainly does. Also, running the regression tests (frequently!) can help you realize when you've broken the existing code before too much time goes by and it's no longer easy to figure out which change is responsible for the breakage. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
