Yow. It's hard to believe that the actual commit (ie, flushing the
commit record to WAL) could take more than a fraction of a second.
I'm thinking there must be a pile of pre-commit work to do, like a
lot of deferred triggers. Do you use deferred foreign keys?
If so, the most likely bet is that the DELETE is triggering a lot
of deferred FK checks, and these are slow for some reason (maybe
another missing index).
