This is required in all Pgpool-II installation.
$ cd pgpool-II-x.x.x/src/sql/pgpool-recovery $ make $ make install
$ psql template1 =# CREATE EXTENSION pgpool_recovery;
$ 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
