[postgis-users] possible problem with PostGIS on RHEL8

Hi Paul,

We are trying to get MapServer and PostGIS installed on RHEL8.2.  We 
have had problems with multiple versions of proj and gdal getting 
installed which is causing the MapServer to link to both and crash.

We are having a hard time finding a version of PostGIS to install which 
does not have Proj8 as MapServer is not ready for that yet.

I think I have found a inconsistency in the gdal32-libs builds.

Here is what I'm looking at:
     postgis31_13-3.1.1-1.rhel8.x86_64.rpm     This uses proj  >= 7.2.1 
& gdal-libs >= 3.2.1  and should work for MapServer

     gdal32-3.2.2-12.rhel8.x86_64.rpm         to meet the above 
requirement - requires gdal32-libs = 3.2.2-12.rhel8
     gdal32-libs-3.2.2-*12*.rhel8.x86_64.rpm *here is the problem*  - 
requires proj80 >= 8.0

When I look at gdal32-libs-3.2.2-*13*.rhel8.x86_64.rpm it also requires 

I see no earlier version of gdal like v3.2.1 so I expected one of the 
gdal-libs above to use proj 7 and the other to use proj8.  Am I wrong to 
expect that? Or am I missing something?

Can you point me to the correct postGIS to use with MapServer on RHEL8?  
Or to someone who might have a solution?
