For a REPLICA IDENTITY FULL remote relation whose local counterpart has no primary key or replica identity, FindUsableIndexForReplicaIdentityFull() chooses the first index of a suitable shape from RelationGetIndexList(). That list excludes only indexes that are not indislive, so an invalid index left behind by a failed CREATE INDEX CONCURRENTLY can be selected. Such an index need not contain every row. Consequently, changes for rows that it fails to find can be silently dropped as missing-tuple conflicts. If the index contains no rows at all, the scan can instead error out and cause the apply worker to exit. Skip invalid indexes, as the planner does.
