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. regards, tom lane
