The results below are untrustworthy. > Segmentation fault (core dumped) Wow --- a core dump in pg_controldata is *really* unexpected, since it's just printing some scalar fields. I can easily believe garbage out, but a crash is harder. I'm beginning to think that there's something wrong with your hand-rolled build, though I have no idea what. Can you get a stack trace out of that?

In my case, I can't line them up, due to restrictions. That doesn't seem to be your problem, at least not yet. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
