      Description

      Note, to avoid this failure in BuildBot, odbc_postgresql is currently
      skipped when run with --embedded.

      Remove this line from storage/connect/mysql-test/t/odbc_postgresql.test:
      --source include/not_embedded.inc

      and run "./mtr --embedded connect.odbc_postgresql".
      It will crash.

      Running "./mtr --valgrind --embedded connect.odbc_postgresql"
      gives some idea of might be wrong:
