Hi
While looking over the spec files for the releases I noticed that the
_vast_ majority of content is the same for each spec.
Where differences exist it isn't always clear why. For example, EL-7
seems to generate an init script differently to EL-6, and the EL-7
packages have postgres_fdw and sepgsql but EL-6 doesn't.
I'm a little curious about why the spec files seem to be copied and
edited, rather than having a single spec for the package across all
supported versions and using conditionals. I'm sure you've thought of
that, so there'll be good reasons - did you try this and run into issues?
As I'm facing the need to do multi-distro patch releases (hotfixes,
basically) where I'll need to rapidly produce new RPMs for each
supported distro, these differences are not fun to deal with, so if
there's a way to use a single spec file and just use conditionals I'd be
pretty happy.
e.g. SuSE defines a %{suse_version} macro, RHEL defines %{rhel} for the
RHEL release, %{fedora} for the fedora release.
rpmbuild --showrc will report defined macros.
If used for builds, mock will define appropriate macros either in the
chroot or by calling rpmbuild.
If I prep a unified spec for postgresql would you be willing to review
and give it a go?
