Bug reference:      16806

PostgreSQL version: 10.15
Operating system:   SUSE Linux Enterprise Server 12 SP5
Description:

Dear PostgreSQL developer team,

when installing postgreSQL10.15 and postgis30_10 for SLES12 SP5 
from the following download repository:
https://download.postgresql.org/pub/repos/zypp/12/suse/sles-12.5-x86_64/
The postgresql packages are installed in the directory path
/usr/lib/postgresql10
while the postGIS packages are using /usr/pgsql-10 as installation
directory.
As a result we have an inconsistent environment.

With the version 10.14 it was correct, it seams.
(output from a different server, also with SLES12 SP5)

Is there a chance to set any environment variable to overwrite the 
installation path when using zypper or rpm for the installation of
postgreSQL 10.15 packages?
