Where does PostgreSQL rank nulls when sorting a column of timestamps, is this
behaviour deterministic, and can I rely on it not changing in the future?
Apologies if this shows up as a repost, I've had gateway problems at this end.

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
