postgresql.dev dependency hell on RedHat

[noelmcloughlin]

Getting postgresql10-devel installed on RedHat os_family is tricky due to dependencies:

• perl-Time-HiRes
• libicu-devel
• perl-IPC-Run
• perl-Test-Simple

Example errors seen

ID: install-postgres-dev-package
    Function: pkg.installed
        Name: postgresql10-devel
      Result: False
     Comment: Error occurred installing package(s). Additional info follows:
              
              errors:

                     Problem 1: cannot install the best candidate for the job
                      - nothing provides perl(Time::HiRes) needed by postgresql10-devel-10.3-1PGDG.f27.x86_64
                     Problem 2: conflicting requests
                      - nothing provides perl(Time::HiRes) needed by postgresql10-devel-10.2-1PGDG.f27.x86_64
                      - nothing provides perl(Time::HiRes) needed by postgresql10-devel-10.3-1PGDG.f27.x86_64

Workaround Fedora

$ sudo dnf install perl-Time-HiRes libicu-devel perl-IPC-Run perl-Test-Simple -y
...

Workaround Centos

$ sudo yum install perl-Time-HiRes libicu-devel perl-IPC-Run perl-Test-Simple -y
...

Finally the state worked.

I use packages-formula to install missing dependencies.
