I want to write some regression tests that confirm the behavior of multiple connections simultaneously going at the same tables/rows. Is there something like this already, e.g. in src/test/regress? In particular I want confirm the robustness of some PL/pgSQL functions in a multi-user environment. I could probably just bang away from multiple interactive psql sessions, but I like to script the whole thing, and I'd like it all to fit neatly into the current "make check" regression tests. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
