NAME

       ocf_heartbeat_pgsqlms - A PostgreSQL multi-state resource agent for Pacemaker

SYNOPSIS

       pgsqlms [start | stop | monitor | promote | demote | notify | reload | methods | meta-data
       | validate-all]

DESCRIPTION

       Resource script for PostgreSQL in replication. It manages PostgreSQL servers using
       streaming replication as an HA resource.

SUPPORTED PARAMETERS

       pgdata
           Location of the PGDATA of your instance

           (optional, string, default "/var/lib/pgsql/data")

       pghost
           The socket directory or IP address to use to connect to the local instance

           (optional, string, default "/var/run/postgresql")

       pgport
           The port to connect to the local instance

           (optional, integer, default "5432")

       bindir
           Location of the PostgreSQL binaries.

           (optional, string, default "/usr/bin")

       system_user
           The system owner of your instance's process

           (optional, string, default "postgres")

       recovery_template
           ONLY for PostgreSQL 11 and bellow.

           The local template that will be copied as the "PGDATA/recovery.conf" file.  This
           template file must exists on all node.

           With PostgreSQL 12 and higher, the cluster will refuse to start if this parameter is
           set or a template file is found.

           (optional, string, default "$PGDATA/recovery.conf.pcmk")

       maxlag
           Maximum lag allowed on a standby before we set a negative master score on it.  The
           calculation is based on the difference between the current xlog location on the master
           and the write location on the standby.

           (optional, integer, default "0" disables this feature)

       datadir
           Path to the directory set in "data_directory" from your postgresql.conf file.  This
           parameter has same default than PostgreSQL itself: the "pgdata" parameter value.

           Unless you have a special PostgreSQL setup and you understand this parameter, ignore
           it

           (optional, string, default to the value of "pgdata")

       start_opts
           Additional arguments given to the postgres process on startup. See "postgres --help"
           for available options. Useful when the postgresql.conf file is not in the data
           directory (PGDATA), eg.:

             -c config_file=/etc/postgresql/9.3/main/postgresql.conf

           (optinal, string, default "")

           op monitor interval=15s timeout=10s role="Master"                      \
           op monitor interval=16s timeout=10s role="Slave"                       \
           op notify timeout=60s

         ms pgsql-ha pgsqld meta notify=true

EXAMPLE PCS
