Correct.  The postgis-#.#.so libraries are designed to be present
side-by-side so that users can do an online upgrade.  But if
postgis-2.0.so gets deleted as soon as 2.1 is installed, then an online
upgrade isn't possible.

It also messes with replication to have the 2.0 library deleted, should
you upgrade the replica before the master, as is common.
