identified by Hiroshi (incorrect cost attributed to OR clauses after multiple passes through set_rest_selec()). I think the code was trying to allow selectivities of OR subclauses to be passed in from outside, but noplace was actually passing any useful data, and set_rest_selec() was passing wrong data. Restructure representation of "indexqual" in IndexPath nodes so that it is the same as for indxqual in completed IndexScan nodes: namely, a toplevel list with an entry for each pass of the index scan, having sublists that are implicitly-ANDed index qual conditions for that pass. You don't want to know what the old representation was :-( Improve documentation of OR-clause indexscan functions. Remove useless 'notclause' field from RestrictInfo nodes. (This might force an initdb for anyone who has stored rules containing RestrictInfos, but I do not think that RestrictInfo ever appears in completed plans.) |
