Default is 1MiB and should be at least 10x larger than any of the MythTV
data requires. However, if a system is configured with a size of 1024
bytes (the smallest you can set), it could have problems post 0.21-fixes
due to the fact that our data can now be potentially 3x larger than it
was in 0.21-fixes due to the character encoding conversion. However,
even with 1024, there are few places where we should have issues with
max_allowed_packet size (most all of our DB data is small).
