That's irrelevant for SQL functions, though, and pg_dump does not need
to worry about dependencies inside other types of functions (since only
SQL functions' bodies are examined during CREATE FUNCTION).
Neil's solution is exactly what I was thinking we should do. Or almost
exactly, anyway: we don't want to run the rewriter before extracting
dependencies.
