Cloudforms : Commented values in postgresql.conf configuration example given in the official Cloudforms documentation

Issue

In the Cloudforms 4.2 Upgrade Document, following is specified :

/var/opt/rh/rh-postgresql95/lib/pgsql/data/postgresql.conf file as described:

-checkpoint_segments = 15   # MIQ Value;
-#checkpoint_segments = 3    # in logfile segments, min 1, 16MB each
+#max_wal_size = 1GB
+#min_wal_size = 80MB

-shared_preload_libraries = 'pglogical'   # MIQ Value (change requires restart)
+shared_preload_libraries = 'pglogical,repmgr_funcs'   # MIQ Value (change requires restart)

+wal_log_hints = on

Should +#max_wal_size = 1GB
+#min_wal_size = 80MB be commented out? and if so why are we adding them to the postgres.conf file?
