Do you have appropriate check constraints defined on table poll? Can
you include a \d poll?
Also, what version is this?
Paul
Sorry, I should have asked: do you have check constraints defined on all
the child poll tables? So, what's \d poll_3 look like, etc? You've
already said you're sure constraint exclusion is on, but you're also
sure postmaster was restarted too?
