Code review comment for lp:~edwin-grubbs/launchpad/bug-535430-needspackaging-timeout-part1

I assume NULL values mean 'has not been calculated yet'. This should be documented in comments.sql.

If we need to retrieve or order rows by bug_count or po_message_count we will need an index on those columns.

Otherwise all looks fine. patch-2207-56-0.sql
