If the 2 tables have different arrangements, then I'm not sure if
there is a quick way. The safest way is probably to do a pg_dump
--attribute-inserts.

Dump data as INSERT commands with explicit column names
(INSERT
INTO table (column, ...) VALUES ...). This will make
restoration
very slow, but it is necessary if you desire to
rearrange the
column ordering.
