Uh, it's not supported *anywhere*, period. If you managed to get the
server to accept a text string with an embedded NUL, I'd like to know
how exactly, because that's a missed validation.

As far as documentation goes, I'd be inclined to address the point
in the page about string data types,

https://www.postgresql.org/docs/current/datatype-character.html

with text along the lines of "The contents of a string value must be
validly encoded according to the database's encoding, and cannot include
the character with code zero". I'd sort of thought we said that there
already, but I don't see it.
