pgsql: Generalize TRUNCATE to support truncating multiple tables in one

-----------
Generalize TRUNCATE to support truncating multiple tables in one
command. This is useful because we can allow truncation of tables
referenced by foreign keys, so long as the referencing table is
truncated in the same command.
