+1 for the concept. The patch looks simple and complete.

I find it strange to use it the way you have shown above, i.e. \gp on
same line after a query.

For me it would be clearer to have tests and docs showing this
  SELECT $1, $2
  \gp 'foo' 'bar'

...since if we used this in a script, it would be used like this, I think...

  SELECT $1, $2
  \gp 'foo' 'bar'
  \gp 'bar' 'baz'
  ...
