I realized that a transition I already did to PG11 was running centos7 and
works just fine (with postgis and all its libs).

The issue appears to be this:

[pryzbyj@database ~]$ sudo cat /var/lib/pgsql/loadable_libraries.txt
could not load library "$libdir/postgis-2.4": ERROR:  could not load library "/usr/pgsql-11/lib/postgis-2.4.so": /usr/pgsql-11/lib/postgis-2.4.so: undefined symbol: geod_polygon_init

[pryzbyj@database ~]$ ldd /usr/pgsql-11/lib/postgis-2.4.so|grep proj
        libproj.so.0 => /lib64/libproj.so.0 (0x00007f5ef6681000)

[pryzbyj@database ~]$ rpm -qf /lib64/libproj.so.0
proj-4.8.0-4.el7.x86_64

[pryzbyj@database ~]$ rpm -qa |grep proj
proj-nad-4.8.0-4.el7.x86_64
proj49-4.9.3-3.rhel7.x86_64
proj-4.8.0-4.el7.x86_64

On the working server, libproj.so.0 finds proj49 (both servers have both
libraries installed).

[pryzbyj@database ~]$ ldd /usr/pgsql-11/lib/postgis-2.4.so |grep proj
        libproj.so.12 => /usr/proj49/lib/libproj.so.12 (0x00007f219c649000)

The postgis24_11 pacakge is pulling in proj/epel, and the PGDG proj49 doesn't
satisfy the dependency.

I worked around the problem on one of the failing servers by copying an older
postgis RPM out of /var/cache on the working server:

        package postgis24_11-2.4.5-1.rhel7.1.x86_64 (which is newer than postgis24_11-2.4.5-1.rhel7.x86_64) is already installed

Hope that helps.
