Segfault at SELECT current_database();

Reproduce:

  1. Run local_ydb with postgres experiment enabled https://github.com/ydb-platform/ydb/wiki/Local-run-postgres-tests
  2. Connect to YDB with psql: psql postgres://root:1234@localhost:5432/local
  3. echo 'SELECT current_database()' | psql postgres://root:1234@localhost:5432/local
