error messages (autovaccum canceled and syntax errors) while loading a DUMP

Hello

A PG dump file was produced on a 11.4. server the usual ways.
When it is loaded with

$ gzip -dc newanna_export.dmp | /usr/local/sisis-pap/pgsql/bin/psql -U sisis sisis

it gives lots of error messages in the server log as:

2020-06-25 12:00:50.333 CEST [31295] ERROR: canceling autovacuum task

2020-06-25 12:00:55.375 CEST [31295] CONTEXT: automatic analyze of table "sisis.public.idm_tasktab"

and also syntax errors like:

What could be the reason for this?
