Server configuration parameters that are classified as local parameters (meaning each segment gets the parameter value from its own postgresql.conf file), should be set identically on all segments. This view shows local parameter settings that are inconsistent. Parameters that are supposed to have different values (such as port) are not included. This view is accessible to all users.

psdname=>The name of the parameter.
psdvalue=>The value of the parameter.
psdcount=>The number of segments that have this value.
