PgPool: distro vs upstream? I'm running PostgreSQL 9.6 and would like to trial pgpool. The yum repository shows the following options:


pgpool-II-96
postgresql-pgpool-II


Which version should i use ? The documentation on PgPool references the first option, but I've found posts on here that say I should use the PostgreSQL specific repository. 

Also are there any useful tutorials on getting this up and running for a first time user, i find the main documentation at pgpool.net confusing?

When I start pgpool i get the following output. 

2018-01-31 17:51:13: pid 41278: DEBUG:  I am 41278
2018-01-31 17:51:13: pid 41278: DEBUG:  initializing backend status
2018-01-31 17:51:13: pid 41278: DEBUG:  authenticate kind = 0
2018-01-31 17:51:13: pid 41278: FATAL:  unable to read data from DB node 0
2018-01-31 17:51:13: pid 41278: DETAIL:  EOF encountered with backend
It just depends on what one you want,


pgpool-II-96 is provided by pgpool.net
postgresql-pgpool-II is provided by your distro.


There is no right answer. Likely, I would go with distro-provided version. It's usually better integrated and I value that more than being more up to date.

As for, 


  FATAL:  unable to read data from DB node 0


That's another question, but it sounds like a connectivity issue.
