The SLES 15.6 repositories are being retired from the main PostgreSQL RPM repository, and are moved to the PostgreSQL ZYPP archive .General support for SUSE Linux Enterprise Server (SLES) 15 SP6 (15.6) ended on December 31, 2025 (by upstream).
All PostgreSQL major versions that were built for these minor releases are available there, including PostgreSQL 18.
If you are still on SLES 15.6 either update to a newer SP (SP7 at the time of this writing), or use the archive. The archived repositories section of the repository packages page generates the repository file and the install commands for each distribution version, architecture and PostgreSQL version:

Please note that these repos will not receive further updates.
If you have any questions, please either email to pgsql-pkg-yum@lists.postgresql.org, or create a ticket at our issue tracker .
