Hi,
I've just inherited an ancient install of 9.1.17 after our
tech guy left, on what turns out to be a rapidly dying server
and being a total newb to PostgreSQL (and not much more
advanced on Linux) I'm a little stuck on the way ahead.
I've managed to secure a decent new server for a new
install of PostgreSQL which runs CentOS 7.6 (Minimal). CentOS
7.6's standard PostgreSQL package seems to be 9.2.24 which is
obviously no longer supported so probably doesn't get us much
further ahead in the short term. As part of this upgrade we'd
also like to implement support for pg_trgm which apparently
needs >=9.6.
I spent most of yesterday trying to get 9.6.13 installed
from the PostgreSQL Yum repository and finally got it working
with the initdb stuff stored on a non-default dedicated
partition (RAID10 array) only to find that psql didn't work
and was complaining about a missing libpq.so.5. Not sure if
that's a common problem?
