Note that that's not an unreasonable decision in itself, if it's done
pursuant to some distro policy that daemons should run with ASLR enabled.
(Right before I left Red Hat, we were looking into building PG with -fPIE
for that reason. It didn't happen yet because of a kernel bug[1], but
it will eventually.)
But there's too many moving parts here for us to know exactly what's going
wrong without more evidence. The only thing that *is* pretty clear is
that the failure is not with the stock PG build anyway, so changing the
properties of the stock build sounds like the wrong response. Personally
I'd think it is the job of the Debian package maintainer to determine why
this is breaking.
