…6275)

If we execute a delete predicate in an inverted index table and then
query something from it, it will cause a core dump in
shrink_char_type_column_suffix_zero. This occurs because the delete
predicate column ID in _char_type_idx is incorrectly shifted to the
result column inserted by the inverted index result.

coredump stack like:
