Hi Thomas,
v_message is of composite data type r_log_message and it's definition is as shown below.
postgres=# \d r_log_message;
Composite type "public.r_log_message"
Column | Type | Collation | Nullable | Default
-------------+-------------------------+-----------+----------+---------
column_name | character varying(30) | | |
oldvalue | character varying(4000) | | |
newvalue | character varying(4000) | | |
Regards,
Aditya.

You don't need a temp table for that. You can create the array directly from the new and old records:
v_message := array[concat_ws(',', 'empName', old.empname, new.empname), concat_ws(',', 'location', old.location, new.location)];
Although nowadays I would probably pass such an "structure" as JSON though, not as a comma separated list.
