[mythtv] Housekeeping of the program table

[usleepless at gmail.com]

Hi All,

i have been strugling to get the scheduler-query in 0.18-fixes perform better.

however, my attention was drawn to the data in the program-table. it
dates back to when i started using mythtv. so i have 8-months worth of
program-guide.

how is this supposed to be handled? is there a housekeeping procedure
which should run, but is not running in my build?

is it normal to retain all acquired program info?

i hope you can help,

regards,

usleep
