Use postgresql-devel instead of postgresql-server-devel on redhat-8

[pat-s]

At the moment, the system dependency postgresql-devel is mapped to postgresql-server-devel on redhat-8:

RPostgres    1.4.7 [bld][cmp][dl] (1.47 MB) + ✖ postgresql-server-devel

However, on rhel8 actually postgresql-devel is required to successfully install RPostgres:

** package ‘RPostgres’ successfully unpacked and MD5 sums checked
** using staged installation
Using PKG_CFLAGS=
Using PKG_LIBS=-lpq
Using PKG_PLOGR=
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libpq was not found. Try installing:
 * deb: libpq-dev libssl-dev (Debian, Ubuntu, etc)
 * rpm: postgresql-devel (Fedora, EPEL)
 * rpm: postgreql8-devel, postgresql92-devel, postgresql93-devel, or postgresql94-devel (Amazon Linux)
 * csw: postgresql_dev (Solaris)
 * brew: libpq (OSX)

Installing postgresql-devel also makes the installation work. Hence, I propose that the current mapping should be changed so that postgresql-devel is installed instead of postgresql-server-devel.

Tested in a new redhat/ubi8 container.

cat /etc/os-release
NAME="Red Hat Enterprise Linux"
VERSION="8.10 (Ootpa)"

Good point, thanks again. These postgresql packages were actually supposed to all be switched to the client packages, but it looks like we missed CentOS/RHEL. I'd like to move over the centos8/fedora rules too, so I can add that to the PR real quick..

Looks like the package is now called libpq-devel since RHEL 8. I moved RHEL 9/Fedora to that too, and tested the RPostgres installation to double check.

Yeah, I saw libpq-devel getting installed so postgresql-devel might only be an (outdated) alias then.

Thanks for checking so quickly!
