dblink_use_rowproc_20120131.patch (text/x-patch) patch

This is fixed version of dblink.c for row processor.

> i'll re-send the properly fixed patch for dblink.c later.

- malloc error in initStoreInfo throws ERRCODE_OUT_OF_MEMORY. (new error)

- storeHandler() now returns FALSE on malloc failure. Garbage
  cleanup is done in dblink_fetch() or dblink_record_internal().
  The behavior that this dblink displays this error as 'unkown
  error/could not execute query' on the user session is as it did
  before.
