IMHO, we should also have a special tag for all the binaries
distributed with these options on the official website (RPM or not).
If the RPM packages' version has been tagged .debug or something like
that, it would have been the first thing I checked.
I like Gregory's idea to add a warning in pgbench. I usually run a few
pgbench tests to check there is no obvious problem even if I use
another more complicated benchmark afterwards. I don't know if that's
what other people do, though.
