I did '\i cd' on solaris.
It doesn't change the directory. It stays where it is.

It is not a bug, it is a feature. Of any Unix, including Solaris,
Linux etc.

Current directory is a propriety of running process.
When process is finished, its current directory is forgotten,
and parent process doesn't know anything about it.

\! in psql starts shell as child process and executes given command in
it. So, executing a command "cd" couldn't affect psql process by design.

If there is a bug, it is that there is no backslash-command to change
working direcory. But there is such command - \cd, at least in 7.2.1
