Thread: alter system command

hi,

I have set archive_command like below:

alter system set archive_command ='pgbackrest --stanza=main archive-push %';

then I reloaded the conf file

select pg_reload_conf();


now when i checked it using the show command like it gave me correct output

postgres=# show archive_command;
             archive_command
-----------------------------------------
 pgbackrest --stanza=main archive-push %


but...

while checking the postgresql.conf file it didn't show me above
output, the parameter acrhive_command is still set with default value

archive_command = '/bin/true/'          # command to use to archive a
logfile segment

So please help me in giving the reason of it that even after reloading
the conf file why it didn't set the value in postgresql.conf file ?


Regards,
Atul

For a more generic option do:

select * from pg_settings where name = 'archive_command';

https://www.postgresql.org/docs/12/view-pg-settings.html

pg_settings will tell you where the server is getting a particular 
setting from.
