Devrim, Jeff:
The current pgdg RPMs for PostGIS remove the older .so files when you
upgrade PostGIS. This is bad policy because it forces the user to shut
down the database application in order to upgrade PostGIS. If the older
libs are left in place, you can do an online upgrade of PostGIS without
a downtime.
Please change the RPMs so that they do not remove the older .so files
when you upgrade.
