Tom Lane b74c543685 Improve usage of effective_cache_size parameter by assuming that all the ... tables in the query compete for cache space, not just the one we are currently costing an indexscan for. This seems more realistic, and it definitely will help in examples recently exhibited by Stefan Kaltenbrunner. To get the total size of all the tables involved, we must tweak the handling of 'append relations' a bit --- formerly we looked up information about the child tables on-the-fly during set_append_rel_pathlist, but it needs to be done before we start doing any cost estimation, so push it into the add_base_rels_to_query scan.		2006-09-19 22:49:53 +00:00
