Subject: Postgres Dump - Creating index never stops

Hello Experts,


we have created a postgres dump using this command: pg_dump pixabay | gzip > pixabay.gz


After restarting postgres (even with a new cluster) and creating a new database, postgres is hanging while extracting the dump: gunzip -c pixabay.gz | psql pixabay


The log file shows that the autovacuum task is running (almost) endless...

What could cause this problem or how can we debug it?

We are running Postgres 9.4 / Ubuntu 16.04

Thanks, Hans
