Why do you need 2.2 RPMs in PostgreSQL 10 repos?

2.3 builds for PostgreSQL 10, 9.6, 9.5, 9.4

We already have 10 for 2.3 upgrade only (though technically I think it would work for more than that)
2.4 is the version that should be officially shipping with PostgreSQL 10.

Your pathing looks a little weird here (why is 2.2.6 embedded in 2.3.6 ?) or is that so you can provide the .so?

/var/lib/pgsql/git/pgrpms/rpm/redhat/master/postgis23/master/postgis-2.3.6/postgis-2.2.6/libpgcommon'

And 2.2.7, 2.3.7 is what we are shipping now 2.2.6/2.3.6

If you really need it that badly, I would suggest making a copy of 2.3.so that you  built for 10 and calling it 2.2.so (it's safer than us trying to backport 10 changes to 2.2)

BTW this very mess is why I wanted to ditch the minor version so the lib would just be called postgis-2 (and we would maintain abi/sql level compatibility which we mostly do already) but lots of people seemed to have issue with that especially doing mid PostGIS 2 series.  It's on the table for PostGIS 3.

2.2 and 2.3 are abi and sql compatible.  2.3 just adds more functions, doesn't take any away that are needed to load 2.2.

Thanks,
Regina
