Conflict with different postgis packages

Hello,

we've tried to install postgis for PostgreSQL 16 and 17 on same server. It is a server for testing different versions
anddoing pg_upgrade between. We got an error when we try to install postgis35_17 if postgis34_16 already installed: 

Error: Transaction test error:
  file /usr/share/man/man1/postgis_restore.1.gz from install of postgis35_17-3.5.0-1PGDG.rhel8.x86_64 conflicts with
filefrom package postgis34_16-3.4.3-2PGDG.rhel8.x86_64 

The installation of same PostGIS version (postgis34_17 and postgis34_16) on same server is possible without any
conflicts.Only if we try to install PostGIS 3.5 for PostgreSQL 17 anstead of PostGIS 3.4 we got this error. Is this
expectedin this case or is it a faulty package configuration? 

Last years we never had problems with differet PostGIS versions. There are installed diffrent postgis version for
differentpostgresql versions on this server: 

$ rpm -qa | grep postgis | sort
postgis31_12-3.1.11-3PGDG.rhel8.x86_64
postgis31_13-3.1.11-3PGDG.rhel8.x86_64
postgis31_14-3.1.11-3PGDG.rhel8.x86_64
postgis33_15-3.3.7-2PGDG.rhel8.x86_64
postgis34_16-3.4.3-2PGDG.rhel8.x86_64
postgis34_17-3.4.3-2PGDG.rhel8.x86_64
