A lot more probably, based on my preliminary tests / my local test script. I'm just not quite sure what the best way is to make it easier to run tests in parallel within the tree. The best I can come up so far is a toplevel target that creates the temp install, starts a cluster and then runs the 'installcheck-or-check' target on all the subdirectories via recursion. Individual makefiles can either use the pre-existing cluster (most of of contrib for example), or use the temporary install and run their pre-existing check target using that (the tap tests, test_decoding, ...). Requires editing a bunch of Makefiles to take advantage. But I don't really see anything that doesn't require that. - Andres -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
