I suspect the above process was ltmp.
So the server has 2 gig of ram with about a dozen MM3 lists on it. Is this an issue with tuning performance of the Postgresql server or do I need to add more memory. I am curious how much ram your server is running and if you had run into any OOM of problems.
I haven't seen any OOM issues on the servers I manage. Those include
mail.python.org 16 GB RAM 261 MM2.1 lists, 139 MM 3 lists
lists.mailman3.org 4 GB RAM and other than tests and demos, only this list
www.grizz.org 8 GB RAM This is my bicycling club's server. 7 MM 2.1 lists, only 2 of which are really active, 7 MM 3 lists including 2 test/demo - MySQL for the club database and Postgres for Mailman 3. It also supports some non Mailman club email and the club's web site including a MoinMoin wiki.
The grizz.org domain was recently migrated from from a larger server in a colo that supported multiple domains to a DigitalOcean droplet which initially had only 4 GB RAM, but that seemed marginally enough at best, so I upgraded it to 8 GB.
So the bottom line is I haven't run Mailman 3 on a server with only 2 GB and that may well not be enough.
