set parameter for all existing session

Hi

I check the “alter database, alter role " and "set " command, but none of
them can set the parameters to all the existing sessions. do we have a
way to do that? looks the "assign_hook" can be used to customize this, is
it a right way to do that?

Maybe you miss to call pg_reload_conf();

example:

alter system set work_mem to '10MB';
select pg_reload_conf();

in other session you can:

show work_mem;

Regards
