When I created the database I set primary key data types as integer; for example: Column | Type | Collation | Nullable | Default --------------+-----------------------+-----------+----------+------------- org_id | integer | | not null | nextval('organizations_org_id_seq'::regclass) I probably should have used the serial type, but didn't. If it would be advisable for me to convert from integer to identity please point me to the appropriate work flow. Reading the CREATE TABLE pages in the manual did not give me sufficient insights to appreciate the differences or indicate how to change the column's data type. Regards, Rich
