Correct Wal_size

[abhishek-intel-smg]

  min_wal_size = optional(object({
    value = optional(string, "8192")
  }))
  max_wal_size = optional(object({
    value = optional(string, "524")

are these the correct values ? max size is less then min size ?

@abhishek-intel-smg It seems like we introduced a bug. That not correct, It should be '524288'.
I'm creating a PR right now, thank you for creating the issue, much appreciated!

Thanks again @abhishek-intel-smg , that's correct.
Fixing now and will discuss with the team additional automation testing to help catch these in the future.
