Massive memory usage in 1.6.4

[AntonOfTheWoods]

I've seen the other issues that say they are fixed. However, I am getting gigabytes of RAM taken after a couple of days with a 1.6.4 running for more than a couple of days. I have 3 jobs running every 5s and 3 every 30s (+ a few others every lots of minutes). If I don't regularly SELECT pg_terminate_backend(pid) from pg_stat_activity where application_name ilike 'pg_cron scheduler'; I simply run out of memory on my db server... Not ideal.

Is this kind of usage simply not supported? How might I see where the issue is?

supabase=# SELECT name, setting FROM pg_settings WHERE name LIKE 'cron.%';
            name             |  setting  
-----------------------------+-----------
 cron.database_name          | supabase
 cron.enable_superuser_jobs  | on
 cron.host                   | localhost
 cron.launch_active_jobs     | on
 cron.log_min_messages       | warning
 cron.log_run                | on
 cron.log_statement          | on
 cron.max_running_jobs       | 32
 cron.timezone               | GMT
 cron.use_background_workers | off

I guess I could just do a daily/bi-daily pg_terminate. Am I wrong to think that's nasty?
