I currently set statement_timeout to 1s to avoid wasting time letting
postgres crunch numbers.  Less than 0.5% of the queries run into this
timeout.

No, I'm currently not logging timing spects.  The schema I let the

I do have some older numbers for line coverage from before the recent
grammar extension:

| revision | overall | parser |
|----------+---------+--------|
| a4c1989  |    26.0 |   20.4 |
