Description:

The assert failed reported in #17334
(https://www.postgresql.org/message-id/17334-135f485c21739caa%40postgresql.org)
has not been repaired.
When executing the following query:

CREATE TABLE point_tbl(f1 point);
CREATE INDEX gpointind ON point_tbl USING gist(f1);
INSERT INTO point_tbl SELECT ('0,0') FROM generate_series(1, 185);
INSERT INTO point_tbl VALUES ('0,NaN');
SET enable_seqscan=off; SELECT f1 <-> point '(0,0)' AS dist FROM point_tbl
ORDER BY dist;

The FailedAssertion("box->low.y <= box->high.y", File:
"/backend/access/gist/gistproc.c") will still occur.
