Yes, I agree! I have found the same solution. I attempted to write Perl tests to verify the patch fix, but the autovacuum process is not triggered in my tests. Could you please assist me?
```
use strict;
use warnings;
use threads;
use PostgreSQL::Test::Cluster;
use PostgreSQL::Test::RecursiveCopy;
use PostgreSQL::Test::Utils;
use Test::More;
use Data::Dumper;
my$node = PostgreSQL::Test::Cluster->new('main');
# Create a data directory with initdb
$node->init;
$node->append_conf(
'postgresql.conf', qq[
autovacuum = on
track_counts=on
autovacuum_naptime = 1s
autovacuum_max_workers = 1
autovacuum_vacuum_threshold = 1
]);
# Start the PostgreSQL server
$node->start;
my$psql1 = $node->interactive_psql('postgres');
$psql1->query("create temp table test (a int primary key);");
