Hi
I have a free time this evening, so I will check this patch
I have a one question
+ /* global temp table get relstats from localhash */
+ if (RELATION_IS_GLOBAL_TEMP(rel))
+ {
+ get_gtt_relstats(RelationGetRelid(rel),
+ &relpages, &reltuples, &relallvisible,
+ NULL, NULL);
+ }
+ else
+ {
+ /* coerce values in pg_class to more desirable types */
+ relpages = (BlockNumber) rel->rd_rel->relpages;
+ reltuples = (double) rel->rd_rel->reltuples;
+ relallvisible = (BlockNumber) rel->rd_rel->relallvisible;
+ }
Isbn't possible to fill the rd_rel structure too, so this branching can be reduced?
Regards
Pavel

I updated the code and remade the patch.
