Tom Lane	3a4f7dde16	Phase 3 of read-only-plans project: ExecInitExpr now builds expression ... execution state trees, and ExecEvalExpr takes an expression state tree not an expression plan tree. The plan tree is now read-only as far as the executor is concerned. Next step is to begin actually exploiting this property.	23 years ago
Tom Lane	1fd0c59e25	Phase 1 of read-only-plans project: cause executor state nodes to point ... 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.	23 years ago

Ok, fair enough. It's worth noting that they've been broken for a while -- for example, the HashJoin counter increments were broken when you comitted r1.20 of executor/nodeHashJoin.c in May of '99. I've attached a revised patch that doesn't remove the counters (but doesn't increment them either: I'm not sure of all the places where the counter should be incremented). Neil Conway	23 years ago
