> things in order I'm attaching the previous patch as well. Patches look good, but I have some notices: 1 step1 Why do you need TabStatHashEntry at all? TabStatHashEntry.t_id is never used for read, so entry for hash could be just a pointer to PgStat_TableStatus. 2 step1 In pgstat_report_stat() you remove one by one entries from hash and remove them all. Isn't it better to hash_destroy/hash_create or even let hash lives in separate memory context and just resets it? 3 step1 Again, pgstat_report_stat(), all-zero entries aren't deleted from hash although they will be free from point of view of pgStatTabList. 4 step 2. The same as 1) about SeenRelsEntry->rel_id but it even isn't initialized anywhere. -- Teodor Sigaev E-mail: teodor@sigaev.ru WWW: http://www.sigaev.ru/
