It needs a test to ensure it only operates on physical slots. It
should ERROR on a logical slot, since it has no way of correctly
advancing the catalog_xmin or finding a reasonable restart_lsn for
I'm still fine with the name, since I plan to add that capability in
pg11 by running through logical decoding and ReorderBufferSkip()ing
each xact until we reach the target lsn.
