I'm not a maintainer. Or any kind of an official "expert". But I'm wondering if the above is really a bug. From reading the documentation on: https://www.postgresql.org/docs/current/static/functions-datetime.html, it seems to me to say that to_timestamp() only takes one parameter, which is a double precision number (not a string). But the following worked well for me:
tsh009=# SELECT '2017-02-20 16:00:27.989808+02'::timestamp;
timestamp
----------------------------
2017-02-20 16:00:27.989808
(1 row)
timestamp
----------------------------
2017-02-20 16:00:27.989808
(1 row)
Or was this an enhancement request?

Nah, that's the other function named to_timestamp. This one's documented
on the previous page:
https://www.postgresql.org/docs/current/static/functions-formatting.html

Possibly. I'm choosing to read it as a complaint that the limitation
is not mentioned in the documentation, which seems to be true. I'll
go fix that.
(Actually supporting TZ/tz might be a bit hard, because you'd have
to figure out how to get to_timestamp's parser to see cases like
"America/New_York" or "GMT-03" as single tokens. Possibly the
omission of OF is just a lack of round tuits.)

Yeah, it's remarkable how many people insist on using to_timestamp
when the regular timestamp input function would serve them as well
or better.

See, I told ya'll that I'm not an expert. And thus it is shown! And in a kindly manner.
