FWIW, the use case on which I've stumbled onto that was use of COPY: as
I understand it, to_timestamp() won't help there, and it's not just
about standards compliance for the sake of it; when reading
(particularly test data) from stdin or a program, it is tempting to use
date(1) from a shell script, or arbitrary ISO 8601 formatting functions.
It's not hard to get around that either, but still would be nice to be
able to rely on standard formats being handled (or perhaps to see it
mentioned in the docs that the support is incomplete).
