Обсуждение: No multi range functions on version 12

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/15/rangetypes.html
Description:

Hello, according to the documentation, Postgres 12 should have multi range
functions. However, in my installation of Postgres 12.12, I don't have any
multi range function. When I ran them Postgres said they didn't exist and I
can't see them when querying through pg_proc.

Multiranges were added in PostgreSQL 14:

"Range types have been extended by adding multiranges, allowing 
representation of noncontiguous data ranges."[1]

I misread the “supported versions” section of the documentation, being new to Postgres. In the following screenshot, I took it to mean that this feature (ranges/multiranges) is supported for the “supported version” as opposed to the platform as a whole:
