This new SQL doesn't seem to be right. Old one doesn't pick up any indexes
other than toast index, but new one seems to do.
Indeed, it was selecting all indexes...
I replaced it by this query reducing the selection of indexes for toast relations:
- "SELECT reltoastidxid "
- "FROM info_rels i JOIN pg_catalog.pg_class c "
- " ON i.reloid = c.oid"));
+ "SELECT indexrelid "
+ "FROM pg_index "
+ "WHERE indrelid IN (SELECT reltoastrelid "
+ " FROM pg_class "
+ " WHERE oid >= %u "
+ " AND reltoastrelid != %u)",
+ FirstNormalObjectId, InvalidOid));
Will send patch soon...
