-- We're having some really weird issues in a production application running on
-- Heroku PostgreSQL 9.3.5. We are seeing a number of long running queries
-- getting stuck inside a transaction (below). We are using PgHero to see and
-- kill the long running queries[1]. Trying to understand what could be
-- happening but we're at a loss.

-- Usually we'll see it idle out at the `UPDATE "sprockets"` line below which
-- causes further updates to that row to block. This bit of code gets run about
-- 1000x per minute for multiple sprockets.
