i dont think i understand the usage properly,
i did the below postgresql.conf
custom_variable_classes = 'general' # list of custom variable
class names
general.employee = ''
am i supposed to see the variable general.employee when i do "show all " ?
i did not see it in fact!
my question is how can i set it and read it
