    In a content moderation system, design a function that takes a post identifier and transforms it into the next available palindromic ID number (reading the same forwards and backwards) that is larger than the current ID, which will be used to flag posts requiring immediate review. The function should return this new palindromic identifier as an integer, ensuring it's the smallest possible palindrome greater than the input ID.
