And if it's there, it might not be writable.

Yeah, I have resorted to putting something like

export PGHOST=/tmp

in all my test scripts, because the above-mentioned issues have affected
Debian for a long time.  Welcome to the party. ;-)

It might actually be useful if the postmaster accepted PGHOST as the
default value for the -k option, just like it accepts PGPORT.  Then this
type setup will become much easier because clients and servers will use
the same defaults.
