I'm kind of surprised there isn't an issue for this yet.

CREATE TABLE bah (
  id INT NOT NULL,
  id2 INT NULL,
  CONSTRAINT "primary" PRIMARY KEY (id ASC),
  CONSTRAINT aaa FOREIGN KEY (id2) REFERENCES bah (id),
  INDEX bah_auto_index_aaa (id2 ASC),
  FAMILY "primary" (id, id2)
)

INSERT INTO bah VALUES (1,1);
pq: foreign key violation: value [1] not found in bah@primary [id]

This fails because we eagerly check the FKs instead of waiting into the end of the statement. But even if we did, I think we would still run into #20041.
That being said, it might be possible to elide this FK check if the values match in the mutation path.

Thanks to the update to allow adding FK constraints on empty tables cockroachdb#32234, the
blacklist needs to be updated.  Sadly, 2 tests now pass, but 4 others now fail
due to cockroachdb#32610.

Fixes cockroachdb#32532.

Can you explain how this issue is not a duplicate of #20041? they seem to exercise the same code path and produce the same error -- I don't see the difference.

As suggested, I'm going to merge the two into one. But this is a slightly different mechanism.

To be clear, this is not yet fixed, just merged this issue with #20041.

The spreadsheet we discussed is unwieldy - hard to edit and impossible to keep
up to date. If we write down blacklists in code, then we can use an approach
like this to always have an up to date aggregation.

So far it seems like there's just a lot of unknowns to categorize still.

The output today:
