9155580 has changed the value of the first fake LSN for unlogged relations from 1 to FirstNormalUnloggedLSN (aka 1000), GiST requiring a non-zero LSN on some pages to allow an interlocking logic to work, but its value was still initialized to 1 at the beginning of recovery or after running pg_resetwal.
