Postgresql 12.5
It's a self-referential FK on a single (but partitioned) table. The ALTER TABLE command fails, but I queried it, and the record that it fails on exists. I modified the original INITIALLY IMMEDIATE clause to INITIALLY DEFERRED but that did not help.
What am I doing wrong?
(We're migrating from Oracle to PostgreSQL, and this is working in Oracle.)
sides=> ALTER TABLE employer_response
ADD CONSTRAINT amended_response_fk FOREIGN KEY (amended_response_id, part_date)

The error:
DETAIL: Key (amended_response_id, part_date)=(103309154, 2021-01-06 00:00:00) is not present in table "employer_response"
is pointing at 103309154 for amended_response_id = employer_response_id. You are showing an employer_response_id of 103309156
But my query's WHERE clause specifies "amended_response_id = 103309154;" (I've highlighted it, if you have a GUI MUA.)
sides=> select employer_response_id, part_date
from strans.employer_response_p2021_01
where amended_response_id = 103309154;
employer_response_id | part_date
