Hi Pgpool-II users,
It has been thought that the meaning of "pool" of "Pgpool" is coming
from "connection pooling". However as Pgpool-II has evolved, Pgpool-II
is not only a simple connection pool software anymore. It has
automatic failover, load balancing, watchdog and more: now Pgpool-II
is effectively a PostgreSQL cluster management software.
So I decided to redefine the meaning of "pool" to be "pool of
PostgreSQL servers". In this direction I have updated the intro
chapter of PostgreSQL manual for the next release (Pgpool-II 4.3).
An HTML compiled version of the chapter can be viewed here:
I hope this change gives people more appropriate view of this
