Installing pgpool_recovery

Pgpool-II need function of pgpool_recovery , pgpool_remote_start and pgpool_switch_xlog , when you use the online recovery that discribes latter. Also pgpoolAdmin of management tool, stop, restart or reload a PostgreSQL on the screen by use pgpool_pgctl . It is enough, if these function installed in template1 fisrt. These function do not needed that install in all databases.

This is required in all Pgpool-II installation.

    $ cd pgpool-II-4.1.1/src/sql/pgpool-recovery
    $ make
    $ make install
   

After this:

    $ psql template1
    =# CREATE EXTENSION pgpool_recovery;
   

or

    $ psql -f pgpool-recovery.sql template1
   

With Pgpool-II 3.3 or later, you need to tweak postgresql.conf . Suppose the path to pg_ctl is /usr/local/pgsql/bin/pg_ctl . Then you add following to postgresql.conf .

    pgpool.pg_ctl = '/usr/local/pgsql/bin/pg_ctl'
   

Probably you want to execute following after this:

    $ pg_ctl reload -D /usr/local/pgsql/data
