documentation – Do same PostgreSQL Limits apply for PostgreSQL 11 version?

I’m writing a research paper in which I’ve been using implementation of PostgreSQL, version 11.8 and what bothers me it’s Docs about DB Limitations (at which is given ONLY for versions 12 and newly released 13. Do these same limits apply to version 11.8 ORR only to those two mentioned versions?

Any guide/help is more than welcome.
