Review Comment:
Hi @beliefer thanks for your comment, I think we have to check it before
calling `catalog.getTableRawMetadata` so that method performs a catalog lookup
as expected rather than reading from the cache (which may be stale). There's
only one call to `catalog.getTableRawMetadata` in this function so we should be
OK here, but thanks for keeping this question in mind :)
