Question: is separate PVC for WAL supported? #1225

Hi! I want to set up a separate disk for storing WAL to speed up postgres performance. Does the operator has such functionality? If not, is it possible to make this with persistence?

"additionalVolumes" Link.

  targetContainers
  volumeSource

pgsql_temp could be stored to separate PVC also. I have not tried additionalVolumes yet in such way, and with non-root usage. Non-root usage would be mandatory for me. It would of course be fast to test.

Additionally: would postgres-operator be able to create such additionalVolumes automatically? Currently data PVCs get created automatically, if those are deleted, I think, ( Only to know how it works. )
