TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
hmm, I waited for at least 1 minute after doing the reload and it was
never updated.
It seemed at the time that the only way to get a updated pg_settings
view was to actually restart the
server. I plan on doing some more testing on Saturday.
