Improve Postgres configuration section in doc
The issue was found during 1.6.0 sanity checks. Source
I successfully installed the server from RPM on Fedora, but it turns out it may not be so trivial to properly configure the Postgres database. Our ARM says this:
The general installation procedure for PostgreSQL is OS-specific
and is not included here. However, please note that Stork uses
pgcrypto extensions, which often come in a separate package. For
example, a postgresql-crypto package is required on Fedora and
postgresql12-contrib is needed on RHEL and CentOS.
which is almost correct, but the newest Fedora keeps the crypto package in postgresql-contrib
rather than postgresql-crypto
. We should probably slightly generalize this text to mention that crypto lib must be installed but do not be so specific what package contains it on what system because it is a moving target.
