Vacuuming did not run on personal_access_tokens table

This might be a minor issue, so feel free to close it out if there's no action necessary. According to Grafana, personal_access_tokens had about 20% dead tuples:

SELECT relname AS TableName, n_live_tup AS LiveTuples, n_dead_tup AS DeadTuples                                                                                                                                                                                        FROM pg_stat_user_tables ORDER by tablename;

Came back with:

<snip>
 personal_access_tokens                   |       2688 |        660

After running VACUUM personal_access_token, the output was:

<snip>
 personal_access_tokens                   |    1801910 |          0

autovacuum_enabled seems to be on.
