Hi Tim,

I see some of these FOREIGN KEY constraint errors every
night. There's a system of speedy and archive tables to keep
short-term queries fast, but it has bugs. There are rows in
the archive tables that should be mirrored in the speedy
tables, but this is not always the case. We (well, mostly
Josh) are working on an improved system of "partitioning"
the huge Postgres tables to keep queries fast which will
hopefully also resolve these referential integrity problems.
