in hopes of reducing platform-to-platform variations in its results. This will cause the geometry regression test to start failing on some platforms. I plan to update the test later today.

precision for float4, float8, and geometric types. Set it in pg_dump so that float data can be dumped/reloaded exactly (at least on platforms where the float I/O support is properly implemented). Initial patch by Pedro Ferreira, some additional work by Tom Lane.

now)" item on the open items, and subsequent plpgsql function I sent in, made me realize it was too hard to get the upper and lower bound of an array. The attached creates two functions that I think will be very useful when combined with the ability of plpgsql to return sets. array_lower(array, dim_num) - and - array_upper(array, dim_num) They return the value (as an int) of the upper and lower bound of the requested dim in the provided array.

the documentation and behavior of "pg_result $res -oid" when $res is not from an INSERT. The documentation says it should return an empty string, but in fact it returns 0. I think it used to return an empty string around PostgreSQL-7.1.3 when PQoidStatus() was used, but now it uses PQoidValue() which returns InvalidOid, 0 in this case. Assuming the current behavior is desired, here is a patch to the documentation doc/src/sgml/libpgtcl.sgml to match what really happens: ljb

not read until after we've read the port-specific header file. In particular this should make it safer to #include system headers for inet_aton; in general it seems that the port header file ought to be in a position to set definitions before we do stuff based on having a definition or not.

node now does its own grouping of the input rows, and has no need for a preceding GROUP node in the plan pipeline. This allows elimination of the misnamed tuplePerGroup option for GROUP, and actually saves more code in nodeGroup.c than it costs in nodeAgg.c, as well as being presumably faster. Restructure the API of query_planner so that we do not commit to using a sorted or unsorted plan in query_planner; instead grouping_planner makes the decision. (Right now it isn't any smarter than query_planner was, but that will change as soon as it has the option to select a hash- based aggregation step.) Despite all the hackery, no initdb needed since only in-memory node types changed.
