To clarify - we've fixed this in Greenplum db - the patch as submitted
is (hopefully) a hint about how to fix it in Postgres, rather than a
working patch... as its full of non-postgres functions and macros:
CdbPathLocus_MakeHashed
cdbpathlocus_pull_above_projection
cdbpullup_findPathKeyItemInTargetList
cdbpullup_makeVar
cdbpullup_expr
Cheers
Mark
