scanning; GiST and GIN do not, and it seems like too much trouble to make them do so. By teaching ExecSupportsBackwardScan() about this restriction, we ensure that the planner will protect a scroll cursor from the problem by adding a Materialize node. In passing, fix another longstanding bug in the same area: backwards scan of a plan with set-returning functions in the targetlist did not work either, since the TupFromTlist expansion code pays no attention to direction (and has no way to run a SRF backwards anyway). Again the fix is to make ExecSupportsBackwardScan check this restriction. Also adjust the index AM API specification to note that mark/restore support is unnecessary if the AM can't produce ordered output.

set_rel_width(). The code had been catering for the possibility of different varnos in the relation targetlist, but this is impossible for a base relation (and if it were possible, putting all the widths in the same RelOptInfo would be wrong anyway).

is NULL but SK_SEARCHNULL is not set. Add checking IS NULL of keys to set during key initialization. If key is NULL and SK_SEARCHNULL is not set then nothnig can be satisfied. With assert-enabled compilation that causes coredump. Bug was introduced in 8.3 by support of IS NULL index scan.

In the previous coding, the list of columns that needed to be hashed on was allocated in the per-query context, but we reallocated every time the Agg node was rescanned. Since this information doesn't change over a rescan, just construct the list of columns once during ExecInitAgg().

according to the TupleDesc's natts, not the number of physical columns in the tuple. The previous coding would do the wrong thing in cases where natts is different from the tuple's column count: either incorrectly report error when it should just treat the column as null, or actually crash due to indexing off the end of the TupleDesc's attribute array. (The second case is probably not possible in modern PG versions, due to more careful handling of inheritance cases than we once had. But it's still a clear lack of robustness here.) The incorrect error indication is ignored by all callers within the core PG distribution, so this bug has no symptoms visible within the core code, but it might well be an issue for add-on packages. So patch all the way back.

Formerly, the lack of any opclasses that could accept such data was enough of a defense, but now with a "record" opclass we need to check more carefully. (You can still use that opclass for an index, but you have to store a named composite type not an anonymous one.)

the timestamp types. Turns out this doesn't even reduce the available range of dates, since the restriction to dates that work for Julian-date arithmetic is much tighter than the int32 range anyway. Per a longstanding TODO item.

depth-first search order. Upon close reading of SQL:2008, it seems that the spec's SEARCH DEPTH FIRST and SEARCH BREADTH FIRST options do not actually guarantee any particular result order: what they do is provide a constructed column that the user can then sort on in the outer query. So this is actually just as much functionality ...

detection.

由 Tom Lane 提交于
pseudo-type record[] to represent arrays of possibly-anonymous composite types. Since composite datums carry their own type identification, no extra knowledge is needed at the array level. The main reason for doing this right now is that it is necessary to support the general case of detection of cycles in recursive queries: if you need to compare more than one column to detect a cycle, you need to compare a ROW() to an array built from ROW()s, at least if you want to do it as the spec suggests. Add some documentation and regression tests concerning the cycle detection issue.
