Thanks!  Just one minor nitpick: setting an %ENV entry to `undef`
doesn't unset the environment variable, it sets it to the empty string.
To unset a variable it needs to be deleted from %ENV, i.e. `delete
$ENV{PGUSER};`.  Alternatively, wrap the relevant tests in a block and
use `local`, like in the `query_log` function.
