Description:

In the following SQL statement, parallel_leader_participation's category is
' Resource Usage / Asynchronous Behavior'

postgres=# select * from pg_settings where
name='parallel_leader_participation';
-[ RECORD 1
]---+--------------------------------------------------------------
name | parallel_leader_participation
setting | on
unit |
category | Resource Usage / Asynchronous Behavior
short_desc | Controls whether Gather and Gather Merge also run
subplans.
extra_desc | Should gather nodes also run subplans, or just gather
tuples?

vartype | bool
source | default
min_val |
max_val |

postgres=#

but in the documents
(https://www.postgresql.org/docs/13/runtime-config-query.html#RUNTIME-CONFIG-QUERY-OTHER)
parallel_leader_participation's category is 'Query Tuning / Other Planner
Options'
and in the category "Asynchronous
Behavior"(https://www.postgresql.org/docs/13/runtime-config-resource.html#RUNTIME-CONFIG-RESOURCE-ASYNC-BEHAVIOR),there
is no parallel_leader_participation parameter.

so, what is parallel_leader_participation's category ?
