Tom Lane 33d3eeadb2 Add a \getenv command to psql. ...

\getenv fetches the value of an environment variable into a psql
variable.  This is the inverse of the \setenv command that was added
over ten years ago.  We'd not seen a compelling use-case for \getenv
at the time, but upcoming regression test refactoring provides a
sufficient reason to add it now.
