Hi Vikas,
For the postgres service, we have the same case (each cluster members has different minor version of 9.6) and there is no problem with that.
But be careful about extensions. Because sometimes an extension can require an upgrade in its db structure otherwise it won't work. So if there is a case like what I describe, you must upgrade the extension before put the server in production.
I don't know about pgpool.

Hi All,
We have Postgresql 9.5 Cluster with streaming replication and pgpool. The version of Postgres is 9.5.5 and Pgpool-II version 3.2.15.
There is now hardware issue with the Standby Machine and it won't startup so we are building new Standby machine.
My question is about the minor version of postgresql 9.5 available now. On postgresql repository site, I can't see postgres 9.5.5 and Pgpool-II-3.2.15 instead there are 9.5.13 and PGpool-II-3.5.15
Is it safe and fine to have postgres 9.5.5 and pgpool-II-3.2.15 on Master & postgres 9.5.13 and Pgpool-II-3.5.15 on Standby ?
Please let me know.
I know the postgres don't keep minor version in PG_VERSION file in data directory so should It be ok to use different minor versions on master & standby?
Thanks in advance.
Regards
Vikas
