Pgbackrest Comparability issue

Hi All,

I am using Pgbackrest and have an issue while upgrading our PostgreSQL
9.5.10 to PostgreSQL 10.4 version on same Physical linux server.
As part of testing I have stop the PostgreSQL 9.5 database on server and
PostgreSQL 10 is up and running and trying to configure and execute the
backups for postgreSQL 10.

I have change the pgbackrest.conf file and trying to create the stanza, it
is throwing *compilation errors*.

*Note :* PostgreSQL 95 backups were configured earlier on same server and
they were successful.

*Details : *
1. instance
postgres 9711 1 0 09:06 pts/1 00:00:00
/u01/postgres/10/bin/postgres -D /u02/pgdata01/10/data
