> 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.
