While the split is reasonable, this change has IMHO one big flaw and
that is the change of the names, which are not really intuitive.

> expected to happen in F30.
>
> We'd like to provide alternative versions of PostgreSQL servers in
> Fedora's modular repo, but still - it is very much desirable to have only
> one version of libpq.so in Fedora (and build all the PostgreSQL server
> versions against that one client library).
>
> So we plan to cut libpq.so.5 soname into separate specfile, dedicated package
> (and ditto for libecpg.so*, and friends).
>
> From packaging POV (of ~120 packages that depend on either postgresql-libs or
> postgresql-devel) nothing huge is happening:
>
> - postgresql-libs is going to disappear, but nothing should depend
> on that package _directly_ (packages who do that by mistake will be
> fixed)
> - 'libpq' will provide/obsolete 'postgresql-libs', and provide
> libpq.so.5()
> - 'libpq-devel' will provide/obsolete 'postgresql-devel'
> (those two ^^ will be done because the majority of affected packages
> only depend on libpq.so.5 anyways)
> - packages with PostgreSQL server modules (third-party *.so plugins) will
> have to switch from BR 'postgresql-devel' to 'postgresql-server-devel',
> and some manual tweaks regarding pg_config will be needed (only few
> packages, prepared in [2])
> - nothing in Fedora so far depends on other sonames from postgresql-libs,
> but such packages should newly depend on libecpg-devel
>
> I've tried to rebuild all "affected" packages with either
> s/BuildRequires: postgresql-devel/libpq-devel/ or
> s/BuildRequires: postgresql-devel/postgresql-server-devel/
> into [2, 3] repos, and everything seemed to be pretty fluent.
>
> So the next step would be to
>
> (a) go through PackageReview of libpq.spec and libecpg.spec,
> (b) rebuild ^^ them, and rebuild postgresql.spec (with related
> changes) into Rawhide and
> (c) rebuild packages that depend on postgresql-libs or postgresql-devel and
> where the rebuild is actually needed (I don't think that I should rebuild
> packages where s/postgresql-devel/libpq-devel/ is enough, since such
> packages depend on libpq.so.5() provide - but let me know if you think
> otherwise). Step
> (d) will be to start working on modular servers, and
> (e) try to build the respective server-side third-party modules against
> that.
>
> For more info please follow the tracker [1], and review changes in [5]
> (compared to postgresql.spec in the actual rawhide) and libpq/libecpg packages
> in 4.
>
> I've also submitted updates for stable Fedoras [6, 7] to provide
> {postgresql-server,libpq,libecpg}-devel Provides, so that any Fedora fix
> that will be done because of this change can be safely merged into the
> stable Fedora branches.

> Thoughts?
