I think it makes sense to do what you suggest, but on the other hand, the original code that Sergey is patching looks like a hack in the sense that it hardcodes which tables to use FREEZE with. There's no point to doing things that way actually, so accepting Sergey's patch to replace that with a relkind check feels sensible to me. I think the query should be SELECT relkind FROM pg_catalog.pg_class WHERE oid='%s'::pg_catalog.regclass if only for consistency with pgbench's other query on catalogs. Your proposal to add different init_steps might be reasonable, at least if we allowed partitionedness of tables to vary in other ways (eg. if we made pgbench_history partitioned), but I don't think it conflicts with Sergey's patch in spirit. -- Álvaro Herrera 48°01'N 7°57'E — https://www.EnterpriseDB.com/ "Here's a general engineering tip: if the non-fun part is too complex for you to figure out, that might indicate the fun part is too ambitious."
