Ok, I found a fix which works for me: don't use ON COMMIT DELETE ROWS on
the temporary tables, but explicitly delete the rows once processed.
However, I think it should work with ON COMMIT DELETE ROWS too, and it

I'd be curious to see what would happen if you added claimnum as a
field in your view. I don't have a complete understanding of the
postgres internals in terms of how it is able to push outer clauses
down in to its views, but I think it might be able to optimize in
that fashion if it is a

Recently our databases started to experience a significant slowdown.

take 150ms or more. This is strange since we are still hitting indexes
