Обсуждение: pg_config docs?

Where do we document the pg_config SQL function?

    test=> \df pg_config
                                     List of functions
       Schema   |   Name    | Result data type |       Argument data types       | Type
    ------------+-----------+------------------+---------------------------------+------
     pg_catalog | pg_config | SETOF record     | OUT name text, OUT setting text | func

I can't find it.

We don't, because it's just the infrastructure under the pg_config view.

Uh, I listed it under "Functions" in the release notes.  Is that the
right place?

If you mean the bit about its mutability marking, I wouldn't bother
listing that in the release notes at all.  It's just a pro-forma change,
because the planner doesn't do anything differently with immutable SRFs.
