sharememory disable is not working

[kannanvr]

Hi Team,
It seems disabling shared memory in the postgres is not handled on the operator code.
We are trying to run Kata container with postgres and kata container is not running with shared memory,
When we disable the shared memory through CRD, we have noticed that it is getting enabled by default.
When we understand the code we found that mountShmVolumeNeeded is returning always true for ebaling the shm memory. It seems opConfig.ShmVolume is always returning true.
Is that any reason we are always returning true from opConfig.ShmVolume?

Thanks,
