The following bug has been logged on the website:
Bug reference: 15845
Logged by: jr
Email address: jean.roch.lefort@gmail.com
PostgreSQL version: 11.0
Operating system: Fedora 29
Description:
The repo I use for Fedora 29 is :
https://download.postgresql.org/pub/repos/yum/11/fedora/fedora-29-x86_64/
and the directory repodata is missing in that repo : thus the installation
cannot be performed because dnf claims that the repo cannot be cached.
(for information : the equivalent for Fedora28 and Fedora30 are ok)
