I immediately see what's up here. WIll fix this in the next short
while. There is no bug here in builds without assertions, but it's
probably best to keep the assertion, and to just make sure not to call
_bt_preprocess_array_keys_final() unless it has real work to do.
Please look at another case, where a similar Assert (but this time in
_bt_preprocess_keys()) is triggered:
CREATE TABLE t (a text, b text);
INSERT INTO t (a, b) SELECT 'a', repeat('b', 100) FROM generate_series(1, 500)
g;
CREATE INDEX t_idx ON t USING btree(a);
BEGIN;
DECLARE c CURSOR FOR SELECT a FROM t WHERE a = 'a';
FETCH FROM c;
FETCH RELATIVE 0 FROM c;

Best regards,
