What is the general difference when handling timestamps?
Postgres: Does not store time zone, only displays column time zone aware.
Oracle:   Stores time zone as part of type.

What does CURRENT_TIMESTAMP return?
Postgres: TIMESTAMP WITH TIMEZONE displaying in session time zone.
Oracle:   TIMESTAMP WITH TIMEZONE in session time zone.

What happens when converting a TIMESTAMP (without time zone) with "AT TIME ZONE '<name>'"?
Postgres: Assumes TIMESTAMP to be in zone <name>.
