Description:        

I was not able to create a postgis 2.5 extensions in postgres 11. The error
was :
SQL Error [XX000]: ERROR: could not load library
"/usr/pgsql-11/lib/postgis-2.5.so": /usr/pgsql-11/lib/postgis-2.5.so:
undefined symbol: geod_polygon_init
  ERROR: could not load library "/usr/pgsql-11/lib/postgis-2.5.so":

[root@ol-pg11 ~]# yum deplist postgis25_11
Loaded plugins: langpacks, ulninfo

I guess the dependency to proj.x86_64 4.8.0-4.el7 should be removed.
