Обсуждение: "IS NOT DOCUMENT" is missing
The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/10/static/functions-xml.html Description: From testing, it seems like PostgreSQL supports the syntax "IS NOT DOCUMENT" in addition to "IS DOCUMENT", similar to "IS NOT NULL", "IS NOT FALSE", etc, however this does not appear to be documented, only "IS DOCUMENT" is.

I'm not sure why it was not documented. It already has some tests. I'll bet that was an oversight. Should we repeat the statement in another item (like the attached patch)? Another option is to add a statement in the "IS DOCUMENT" item. I'm afraid that NULL return wouldn't be clear. -- Euler Taveira Timbira - http://www.timbira.com.br/ PostgreSQL: Consultoria, Desenvolvimento, Suporte 24x7 e Treinamento

Thank.s Per the nearby discussion, this should probably also be backpatched further. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
