Обсуждение: BUG #18336: Inconsistency in PostgreSQL 16 Documentation for SHOW Command

The following bug has been logged on the website:

Bug reference:      18336
Logged by:          Yuta MASANO
Email address:      masano@sraoss.co.jp
PostgreSQL version: 16.1
Operating system:   Not Applicable - Documentation Issue
Description:

In the PostgreSQL 16 release notes, there is an entry stating that the
read-only server variables lc_collate and lc_ctype have been removed.
However, the documentation for the SHOW command on the PostgreSQL official
website (https://www.postgresql.org/docs/current/sql-show.html) still lists
lc_collate and lc_ctype as valid variables. This discrepancy suggests that
the documentation has not been updated to reflect the removal of these
variables. This report is to request clarification and, if necessary, an
update to the documentation to accurately represent the current state of
these server variables in PostgreSQL 16.

Right; here is a patch for that.

I think the whole list of read-only options on the SHOW reference page 
is redundant and incomplete.  A more complete list is at <sect1 
id="runtime-config-preset"> in config.sgml.  This includes 
server_version and server_encoding, but not is_superuser.  Maybe that's 
an omission?  I think we should get rid of the list on the SHOW 
reference page.

That is much better; here is a patch.
