My fuzzer finds a bug in Postgres, which makes the connection closed
unexpectedly. This bug still can be reproduced even after applying the
patch for
https://www.postgresql.org/message-id/flat/b2bd02dff61af15e3526293e2771f874cf2a3be7.camel@cybertec.at
--- Steps to reproduce the bug ---
1. /usr/local/pgsql/bin/psql -d postgres -c "drop database redb";
2. /usr/local/pgsql/bin/psql -d postgres -c "create database redb";
3. /usr/local/pgsql/bin/psql -d redb -f pg_testdb55_bk.sql;
4. /usr/local/pgsql/bin/psql -d redb -f unexpected.sql
pg_testdb55_bk.sql and unexpected.sql are attached.
--- Expected behavior ---
No error triggered.
--- Actual behavior ---
The test case makes the connection closed unexpectedly:
psql:unexpected.sql:695: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
psql:unexpected.sql:695: error: connection to server was lost
