The copy paste problem also frustrates me, maybe modifying the prompt
isn't an effective answer though.

Extending the history command (\s) sounds more promising
\s- for a reverse ordered history
\s[n] for the last n or n-from-last-th (\s1 different from \p in that
it shows the last completed query not the one in progress)

and most importantly showing full history through a less-style
interface like large result sets rather than in the flow of psql

Does that sound like a workable answer?
