Anthony,
As per my knowledge, this can't work on pg84 dump/restore too. You should
match timezone on restoring database with the dump database to load it
successfully. You can set at user level or database level.
On restoring database:
ALTER DATABASE test_db_2 SET TIMEZONE TO 'UTC';
OR
ALTER USER postgres SET TIMEZONE TO 'UTC';
Hope , it will help.
