operator strategy numbers, ie, GiST and GIN. This is almost cosmetic enough to not need a catversion bump, but since the opr_sanity regression test has to change in sync with the catalog entry, I figured I'd better do one.

are all in new-in-8.2 logic associated with indexability of ScalarArrayOpExpr (IN-clauses) or amortization of indexscan costs across repeated indexscans on the inside of a nestloop. In particular: Fix some logic errors in the estimation for multiple scans induced by a ScalarArrayOpExpr indexqual. Include a small cost component in bitmap index scans to reflect the costs of manipulating the bitmap itself; this is mainly to prevent a bitmap scan from appearing to have the same cost as a plain indexscan for fetching a single tuple. Also add a per-index-scan-startup CPU cost component; while prior releases were clearly too pessimistic about the cost of repeated indexscans, the original 8.2 coding allowed the cost of an indexscan to effectively go to zero if repeated often enough, which is overly optimistic. Pay some attention to index correlation when estimating costs for a nestloop inner indexscan: this is significant when the plan fetches multiple heap tuples per iteration, since high correlation means those tuples are probably on the same or adjacent heap pages.

joinclause doesn't use any outer-side vars) requires a "bushy" plan to be created. The normal heuristic to avoid joins with no joinclause has to be overridden in that case. Problem is new in 8.2; before that we forced the outer join order anyway. Per example from Teodor.

representing externally-supplied values, since the APIs that carry such values only specify type not typmod. However, for PARAM_SUBLINK Params it is handy to carry the typmod of the sublink's output column. This is a much cleaner solution for the recently reported 'could not find pathkey item to sort' and 'failed to find unique expression in subplan tlist' bugs than my original 8.2-compatible patch. Besides, someday we might want to support typmods for external parameters ...
