Master parameter settings in the master postgresql.conffile are the system-wide default. To set a master parameter:

1. Edit the $MASTER_DATA_DIRECTORY/postgresql.conf file.
2. Find the parameter to set, uncomment it (remove the preceding # character), and type the desired value.
3. Save and close the file.
4. For session parameters that do not require a server restart, upload the postgresql.conf changes as follows:

1. $ gpstop -u 5. For parameter changes that require a server restart, restart Greenplum Database as follows:

1. $ gpstop -r

For details about the server configuration parameters, see the Greenplum Database Reference Guide.
