Note: The following instructions use the PGDATA and PGVER environment variables. See supplementary content APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER.

To change the listening port of the database, as the database administrator, change the following setting in postgresql.conf: 

$ sudo su - postgres 
$ vi $PGDATA/postgresql.conf 
Change the port parameter to the desired port. 

Next, restart the database: 

$ sudo systemctl restart postgresql-${PGVER?} 

Note: psql uses the port 5432 by default. This can be changed by specifying the port with psql or by setting the PGPORT environment variable: 

$ psql -p 5432 -c "SHOW port" 
$ export PGPORT=5432

PostgreSQL must disable network functions, ports, protocols, and services deemed by the organization to be nonsecure, in accord with the Ports, Protocols, and Services Management (PPSM) guidance.
