The following bug has been logged on the website: Bug reference: 15723 Logged by: Anna Muravieva Email address: ana-mur21s@yandex.ru PostgreSQL version: 9.6.1 Operating system: linux Description: Hello We have currently that issue. "worker process died unexpectedly" was caused by the lock on the table, which was generated because of the truncate we use. This seems to cause the Postgres pg_dump worker process to exit abnormally. Why this is not an Error or Warning in Postgres or pg_dump, What we see is that pg_dump exits at this point and has not exported part of the database. Again this feels like a Bug with Postgres or pg_dump. Could you please help to understand Thank you appreciated for help Anna

Again this feels like a Bug with Postgres or pg_dump. Could you > please help to understand 9.6.1 is pretty old, and since then we've fixed a number of bugs in pg_dump and/or pg_restore that could cause problems in parallel restores. Please update to current (9.6.12) and see if the problem still occurs. If it is still there, you'd need to provide more details, like what SQL command fails exactly. regards, tom lane
