Here's a review for the V2 patch: I noticed this change to buffile.c shows up in both v1 and v2 of the patchset, but I can't trace the reasoning why it changed with this patch (rather than a separate bugfix): > +++ b/src/backend/storage/file/buffile.c > @@ -867,7 +867,7 @@ BufFileSize(BufFile *file) > { > int64 lastFileSize; > > - Assert(file->fileset != NULL); > + Assert(file->files != NULL); > +++ b/src/backend/commands/explain.c > [...] > +show_material_info(MaterialState *mstate, ExplainState *es) > + spaceUsedKB = (tuplestore_space_used(tupstore) + 1023) / 1024; I think this should use the BYTES_TO_KILOBYTES macro for consistency. Lastly, I think this would benefit from a test in regress/sql/explain.sql, as the test changes that were included removed the only occurrance of a Materialize node from the regression tests' EXPLAIN outputs. Kind regards, Matthias van de Meent
