I sometimes do some testing as nobody, on a distro where
getpwent(nobody)->pw_dir is a directory that nobody can't write.
So I end up setting $HOME to a directory that, um, is writable.
When I start psql, strace shows $HOME being honored when looking
for .terminfo and .inputrc, and getpwent()->pw_dir being used
to look for .pgpass, .psqlrc, and .psql_history, which of course
aren't there.
I'm sure the .terminfo and .inputrc lookups are being done by library code.
In my experience, it seems traditionally unixy to let $HOME take precedence.
