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. 2002-12-05 10:50:39 -05:00			`#include "nodes/execnodes.h"`
Cleanup up include files. 1997-11-25 20:14:33 -05:00
Used modified version of indent that understands over 100 typedefs. 1997-09-08 17:56:23 -04:00			`extern int ExecCountSlotsGroup(Group *node);`

pgindent run over code. 1999-05-25 12:15:34 -04:00
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 12:46:40 -05:00			`#endif /* NODEGROUP_H */`
