PG11rc1 / centos7; and, RH6 schedule

Hi,

Wanted to point out that PG11rc1 isn't installable centos7 due to dependencies:

Error: Package: postgis24_11-2.4.5-1.rhel7.x86_64 (pgdg11)
           Requires: SFCGAL
Error: Package: postgis24_11-2.4.5-1.rhel7.x86_64 (pgdg11)
           Requires: libSFCGAL.so.1()(64bit)
Error: Package: gdal-libs-1.11.4-12.rhel7.x86_64 (pgdg11)
           Requires: libgeotiff.so.2()(64bit)

I worked around it by installing repo for PG10:

Also, I'm still wondering how long we can expect updates for RH6 to continue?
It'd be good to have a plan for patchlevel updates or major releases.

Thanks,
