When replaying a DROP TABLE SPACE, you first try to remove the
directory, and if that fails, you assume that it's because it's in use
as a temp tablespace in a read-only transaction. You then call
ResolveRecoveryConflictWithVirtualXIDs to kill such transactions, and
try removing the directory again. But
ResolveRecoveryConflictWithVirtualXIDs doesn't wait for the target
transaction to die anymore (or at least it shouldn't, as we discussed
earlier), so that doesn't work AFAICS.
One quick work around would be to simply not respect temp_tablespace
during recovery...
