Problem Description:
--------------------
when a table exceeds 2gb, it appears that postgres will create subfiles for the data.
when you rename a table, the sub files do no get renamed.
see backend/commands/rename.c [renamerel()]
--------------------------------------------------------------------------
Test Case:
----------
create a table in excess of 2gig, which in turn creates subfiles
in data/base/tabname.
rename the table.
the subfiles are not renamed.
--------------------------------------------------------------------------
Solution:
---------
possible solution is to check if the table has subfiles, look for those subfiles and rename them as well.
