Two things to notice: 1)  It has no key; and 2) it's in pending destroy
state.

This implies to me that is is being used as a private shared memory
area for the postgres server and its forked children.  This is very
probably something to do with transaction management and internal
process control.  I assume something on the system requires postgres?
If not you can probably just disable it using 'chkconfig', or distro's
equivalent.
