I realize it's not going to be popular, but I'd love to have 'trust'
only allowed if a command-line option is passed to the postmaster or
something along those lines. It's really got no business being an
option for a network service like PG. I'd suggest ripping it out
entirely but I'm sure that'd be even less popular and Andrew does make a
good point that our single-user-mode is still so terrible that we have
to support a multi-user-mode with zero auth, to deal with certain kinds
of breakage/corruption. The fix for that is having a real single-user
mode that is usable, as has been discussed previously, but we don't seem
to be making much progress in that direction, unfortunately.
Thanks!
