I have cited the implementation in the other RDBMS because it helps to
understand the feature, it shows the state of the art on it and
illustrates my needs. If making references to other implementation turns
people against me I think that they have the wrong approach on this
proposal and if we refuse feature because they are implemented in other
RDBMS this is even worst. I'm not agree with this comment.

For what I've read in this thread
https://www.postgresql.org/message-id/flat/20210501072458.adqjoaqnmhg4l34l%40nol
there is no real consensus in how implementing this feature should be
done. But I agree that if the implementation through an extension was
possible I would not write a patch to core but an extension, this is my
common behavior.
