Yes, particularly for pg_dumpall scripts...

For my purposes this would be acceptable, but I wouldn't actually want
to use 0200.  So it'd be nicer if the default socket permission were
trivially configurable (ideally as a configure switch).  Given that,
I wouldn't mind if the default were 0200.

Note that locking down the unix socket is little help if one is using a
startup script that helpfully supplies -i by default.  I am not sure
what the score is with all the startup scripts that are in various RPMs
and other platform-specific distributions; does anyone know if there are
any that ship with -i enabled?
