Peter Serwylo 5e263c0e0f Use "COALESCE(x, 0)" instead of "x = 0 OR x IS NULL"
This is a more concise syntax to say the same thing, and avoids an
OR clause in the where - which is often the cause of slowness in
many queries. Not sure if it was problematic in these cases, however
this COALESCE syntax is still more consise.
