ERROR: column "time2" cannot be cast to type timestamp without time zone
you need to give it some hints as to how to do that casting.
ALTER TABLE sixty_min ALTER COLUMN time2 TYPE timestamp USING
to_timestamp(time2, 'YYYY-MM-DD HH24-MI-SS');
I would use timezone with time zone as the type here. Effectively, this
type converts all input times to UTC from either the specified or
client's default TZ, and converts all time output to either the
specified or client's TZ. it behaves properly, while 'timestamp'
without timezone doesn't..
