postgresql – Do Postgres triggers work with Heroku?

My local postgres db triggers work fine but the do not fire on my deployed Heroku instance.

The functions are installed:

project::DATABASE=> dft
                             List of functions
 Schema |       Name       | Result data type | Argument data types | Type 
--------+------------------+------------------+---------------------+------
 public | edit_appointment | trigger          |                     | func
 public | new_appointment  | trigger          |                     | func
(2 rows)

When I try to show details I get an error:

project::DATABASE=> d appointment_schedule 
ERROR:  column c.relhasoids does not exist
LINE 1: ...riggers, c.relrowsecurity, c.relforcerowsecurity, c.relhasoi...

I was able to install the trigger and the function but the don’t fire:

project::DATABASE=> select * from appointment_schedule where objid = 25;
 objid |          created           | lesson_detail_id | lesson_info | time_increment_id | start_time | end_time | lesson_type | instructor_id | instructor | client_id | client | confirmed | last_edit 
-------+----------------------------+------------------+-------------+-------------------+------------+----------+-------------+---------------+------------+-----------+--------+-----------+-----------
    25 | 2021-04-03 02:08:58.933837 |                1 |  Day ->     |                   |            |          |             |               |            |           |        |           |

Update the record which should give a start time and end-time in those columns

project::DATABASE=> update appointment_schedule set time_increment_id = 8 where objid=25;                   
UPDATE 1

Results:

project::DATABASE=> select * from appointment_schedule where objid = 25;                 
 objid |          created           | lesson_detail_id | lesson_info | time_increment_id | start_time | end_time | lesson_type | instructor_id | instructor | client_id | client | confirmed | last_edit

    25 | 2021-04-03 02:08:58.933837 |                1 |  Day ->     |                 8 |            |          |             |               |            |           |        |           | 
(1 row)

I don’t know what’s happening here.

Some help from anyone who knows postgres on Heroku please?
