Start with the stack trace entry points IdoPgsqlConnection::Query and InternalExecuteQuery, then investigate why query-string construction reaches std::bad_alloc. Review the upgrade-related behavior and available database diagnostics; done means identifying a reproducible cause, preventing the daemon crash, and adding a regression test.
