Setting Parameters at the System Level

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

1. Edit the $COORDINATOR_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:

   $ gpstop -u
   

5. For parameter changes that require a server restart, restart Greenplum Database as follows:

   $ gpstop -r
   

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