This is really neat work, and thanks for the patch.

This issue in this one as in the crosstab extension is that it's
available only if you are using some particular piece of extra
software, in this case the psql client.

I'm working up a proposal to add (UN)PIVOT support to the back-end.
Would you like to join in on that?

Cheers,
David.
