thank you very much for pointing me to dynahash, here is the next version that finally seems to work.Two patches are attached, the first is the absolute minimum for making it work, this still has the Tree type for canon_pathkeys and eq_classes got the same treatment as join_rel_list/join_rel_hash has in the current sources: if the list grows larger than 32, a hash table is created. It seems to be be enough for doing in for get_eclass_for_sort_expr() only, the other users of eq_classes aren't bothered by this change.
That's better, but can't you use dynahash for canon_pathkeys as well? -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
