It can reproduce reliably with the three scripts attached:

psql -c' drop table if exists t; create table t (a serial primary key, b int, c int);' && pgbench -n -c 4 -T300 -f
/tmp/insert.sql
pgbench -n -c 4 -T300 -f /tmp/vacuum.sql
pgbench -n -c 4 -T300 -f /tmp/analyze.sql

Locally that triggers the problem within usually a few seconds.
