Postgres always was a bit hackerish, allowing slightly more then is safe. I.e. you can define immutable function that is not really immutable, turn off autovacuum or fsync. Why bother with safety guards here?
My opinion is that we should have this function to extract timestamp. Even if it can return strange values for imprecise RFC implementation.

OK, it seems like we have some consensus on ERRORing..

Do we have any other open items? Does v13 address all open items? Maybe let’s compose better error message?

+1 for erroring when ts is outside range.

v13 looks good for me. I think we have reached a optimal compromise.
