"constructor" does not work as alias for me

[Marcus Strube <strube1974@xxxxxxxxx>]

Hi,

the alias "constructor" does seem to be a problem.

select n as "constructor" from (VALUES (1), (2), (3)) AS t (n)

This gives this result: https://imgur.com/a/dM9eM06

psql for both gives the same result.

I am running the latest version from the "PostgreSQL Apt Repository" on Ubuntu 18.10 in desktop mode.

Regards,

Marcus
