I think that there is a good case for preferring this behavior. While
it is a little confusing that pg_stat_statements does not change the
representative query string, renaming a table does not make it a
substantively different table.
There is, IIRC, one case where a string is jumbled directly (CTE
name). It's usually not the right thing, IMV.
