Code review for commit dc203dc3ac40a4b02b92fb827848a547d2957153.

Remove duplicate assignment.  This part by Ashutosh Bapat.

Remove now-obsolete comment.  This part by me, although the pending
join pushdown patch does something similar, and for the same reason:
there's no reason to keep two lists of the things in the fdw_private
structure that have to be kept in sync with each other.

  * Indexes of FDW-private information stored in fdw_private lists.

- * We store various information in ForeignScan.fdw_private to pass it from

- *
- * 1) SELECT statement text to be sent to the remote server
- * 2) Integer list of attribute numbers retrieved by the SELECT
- *
  * These items are indexed with the enum FdwScanPrivateIndex, so an item
  * can be fetched with list_nth().  For example, to get the SELECT statement:
  *		sql = strVal(list_nth(fdw_private, FdwScanPrivateSelectSql));
