Then per Amitabh Kant's suggestion take a look at the cycle setting for the sequences. For sequence named ts_stamp_test_id_seq: test=# select * from ts_stamp_test_id_seq ; -[ RECORD 1 ]-+--------------------- sequence_name | ts_stamp_test_id_seq last_value | 6 start_value | 1 increment_by | 1 max_value | 9223372036854775807 min_value | 1 cache_value | 1 log_cnt | 0 is_cycled | f is_called | t You are looking for whether is_cycled = t Per the docs: https://www.postgresql.org/docs/9.6/static/sql-createsequence.html "CYCLE NO CYCLE The CYCLE option allows the sequence to wrap around when the maxvalue or minvalue has been reached by an ascending or descending sequence respectively. If the limit is reached, the next number generated will be the minvalue or maxvalue, respectively. If NO CYCLE is specified, any calls to nextval after the sequence has reached its maximum value will return an error. If neither CYCLE or NO CYCLE are specified, NO CYCLE is the default.
