Use the correct PG_DETOAST_DATUM macro in BRIN Commit 6bcda4a721 replaced PG_DETOAST_DATUM with PG_DETOAST_DATUM_PACKED in two BRIN output functions, for minmax-multi and bloom opclasses. But this is incorrect - the code is accessing the data through structs that already include a 4B header, so the detoast needs to match that. But the PACKED macro may keep the 1B header, which means the struct fields will point to incorrect data.
