* Convert hash join code to use MinimalTuple format in tuple hash tableTom Lane2006-06-271-2/+2

* Extend the ExecInitNode API so that plan nodes receive a set of flagTom Lane2006-02-281-2/+2
| | | | | | | | | | | | bits indicating which optional capabilities can actually be exercised at runtime. This will allow Sort and Material nodes, and perhaps later other nodes, to avoid unnecessary overhead in common cases. This commit just adds the infrastructure and arranges to pass the correct flag values down to plan nodes; none of the actual optimizations are here yet. I'm committing this separately in case anyone wants to measure the added overhead. (It should be negligible.) Simon Riggs and Tom Lane

* Revise hash join code so that we can increase the number of batchesTom Lane2005-03-061-3/+5
| | | | | | | on-the-fly, and thereby avoid blowing out memory when the planner has underestimated the hash table size. Hash join will now obey the work_mem limit with some faithfulness. Per my recent proposal (hash aggregate part isn't done yet though).

| | | | | | | | Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

* Phase 1 of read-only-plans project: cause executor state nodes to pointTom Lane2002-12-051-6/+7
| | | | | | | | | | to plan nodes, not vice-versa. All executor state nodes now inherit from struct PlanState. Copying of plan trees has been simplified by not storing a list of SubPlans in Plan nodes (eliminating duplicate links). The executor still needs such a list, but it can build it during ExecutorStart since it has to scan the plan tree anyway. No initdb forced since no stored-on-disk structures changed, but you will need a full recompile because of node-numbering changes.

* Split 'BufFile' routines out of fd.c into a new module, buffile.c. ExtendTom Lane1999-10-131-1/+2
| | | | | | | | BufFile so that it handles multi-segment temporary files transparently. This allows sorts and hashes to work with data exceeding 2Gig (or whatever the local limit on file size is). Change psort.c to use relative seeks instead of absolute seeks for backwards scanning, so that it won't fail when the data volume exceeds 2Gig.
