Hello Folks,

Using AWX 23.9.0 with postgres 13 under k3s.

Vacuum commands are failing as below:  
`ERROR: could not resize shared memory segment "/PostgreSQL.226752521" to 67145696 bytes: No space left on device`

Believe this is a limitation with kubernetes & /dev/shm size cannot be increased.

Googling gave below option:  
`https://stackoverflow.com/questions/43373463/how-to-increase-shm-size-of-a-kubernetes-container-shm-size-equivalent-of-doc`

However, don’t find an option to mount volume in postgres pod.  
`https://ansible.readthedocs.io/projects/awx-operator/en/latest/user-guide/advanced-configuration/custom-volume-and-volume-mount-options.html`

Request thoughts & inputs on how to get going.
