Hi  
What is the value for a particular replica?  
What do you mean between two points?

tried adding a replica name. like this - not working  
without a replica name does not work either

```auto
  pgReplicas:
    hotStandby:
      size: 1
    nsi-repl1:
      volumeSpec:
        size: 1G
        accessmode: ReadWriteOnce
        storagetype: create
        storageclass: ""
        matchLabels: "pv=nsi-repl"

```

for pgPrimary this place looks like this and works as it should

```auto
  pgPrimary:
    volumeSpec:
      size: 1G
      accessmode: ReadWriteOnce
      storagetype: create
      storageclass: ""
      matchLabels: "pv=nsi-prim"

```

How to correctly specify the value for a specific replica?

It comes out like this: pgReplicas.hotStandby.volumeSpec  
With one replica it worked correctly like this.

```auto
  pgReplicas:
    hotStandby:
      size: 1
      volumeSpec:
        size: 1G
        accessmode: ReadWriteOnce
        storagetype: create
        storageclass: ""
        matchLabels: "pv=nsi-repl"

```
