AFAIR at the moment of implementing that part the 7.3 doc didn't fully
document pg_constraint. The correct answer to this question now is
pg_constraint.confmatchtype.

We'll fix this for 1.3/1.4. It requires dialog changes, so this has to
wait a little. Thanks for pointing out this missing option, we'd
probably would have missed it up to pgsql 2030 :-)
