Then I made a change in Eigenchange 7496 that resulted in that estimated row count no longer being needed. But I forgot to remove the call in SortRel. Since it's no longer being used, it should be safe to remove it.

[reporter="jvs", created="Mon, 28 Jan 2008 22:57:47 -0500 (GMT-05:00)"] Currently, it does this:
// save the input row count while we still have logical RelNodes
estimatedNumRows = RelMetadataQuery.getRowCount(child);
This looks like something added as a hack for LucidDB's optimizer.
