Re: invalid value for parameter "default_text_search_config": "public.pg"

However, the parallel worker should just be absorbing the same
configuration settings your main session is using.  So what remains
to be explained is why you aren't seeing the same complaint when
starting a fresh session.  It might be useful to look at the
output of

show default_text_search_config;

and

select * from pg_file_settings where name = 'default_text_search_config';

psql (15.3 (Debian 15.3-1.pgdg110+1))
Type "help" for help.

mydatabase=# show default_text_search_config;
 default_text_search_config
----------------------------
 public.pg
(1 row)

mydatabase=# select * from pg_file_settings where name = 'default_text_search_config';
                 sourcefile                 | sourceline | seqno |            name            |  setting  | applied |            error            
--------------------------------------------+------------+-------+----------------------------+-----------+---------+------------------------------
 /opt/postgresql/data/conf.d/06_locale.conf |         17 |    24 | default_text_search_config | public.pg | f       | setting could not be applied
(1 row)

mydatabase=#

I'm not sure what applied="public.pg", error="setting could not be applied" means. I can change it in the config file, no problem. I just would like to know if this is a simple configuration error, or a software installation error. (Is public.pg a built-in config that should always exist?)
