Robert Haas 76733b399c Avoid using a fake relcache entry to own an SmgrRelation. 
If an error occurs before we close the fake relcache entry, the the
fake relcache entry will be destroyed by the SmgrRelation will
survive until end of transaction. Its smgr_owner pointer ends up
pointing to already-freed memory.

The original reason for using a fake relcache entry here was to try
to avoid reusing an SMgrRelation across a relevant invalidation. To
avoid that problem, just call smgropen() again each time we need a
reference to it. Hopefully someday we will come up with a more
elegant approach, but accessing uninitialized memory is bad so let's
do this for now.
