A security patch changed them today, so close the coverage gap now. Test that buffer overrun is avoided when pg_mblen*() requires more than the number of bytes remaining. This does not cover the calls in dict_thesaurus.c or in dict_synonym.c. That code is straightforward. To change that code's input, one must have access to modify installed OS files, so low-privilege users are not a threat. Testing this would likewise require changing installed share/postgresql/tsearch_data, which was enough of an obstacle to not bother.
