I followed this workaround, which is nicely summarized at
https://github.com/postfixadmin/postfixadmin/issues/381#issuecomment-678269198

Yet, not all errors are suppressed this way:

$ doveadm pw
doveadm(olav): Error: net_connect_unix(/run/dovecot/stats-writer) failed: Permission denied

$ ls -l /run/dovecot/stats-writer
srw-rw---- 1 root    dovecot    0 11. Sep 00:27 stats-writer
