Here is a refer to the stackoverflow question:

it carry another example and the solution however I still think that
this fuctionality should be avliable in a build-in postgresql function.
This would be a new feature and Postgres only introduces new features in
new major version releases. The next major release is 10 and it is the
latter stages of development. Not sure if there is a feature freeze on
yet or not. In any case it will not be released for production until
fall sometime(best guess, I have nothing to do with release schedule).
If it did not make it into that release you are looking another year
out. So if this is something you need soon, then I would say the
solution would be to create your own function using the suggestions
provided. If you really want this as a built in, regardless of when it
is done I would suggest either filing bug:

or
post to the --hackers list:
