Fix ExecSubPlan to handle nulls per the SQL spec --- it didn't combine nulls with non-nulls using proper three-valued boolean logic. Also clean up ExecQual to make it clearer that ExecQual does follow the SQL spec for boolean nulls. See '[BUGS] (null) != (null)' thread around 10/26/99 for more detail. 1999-11-12 07:39:34 +01:00			`extern Datum ExecSubPlan(SubPlan node, List pvar, ExprContext *econtext,`
Ye-old pgindent run. Same 4-space tabs. 2000-04-12 19:17:23 +02:00			`bool *isNull);`

pgindent run before 6.3 release, with Thomas' requested changes. 1998-02-26 05:46:47 +01:00			`extern void ExecReScanSetParamPlan(SubPlan node, Plan parent);`
First stage of reclaiming memory in executor by resetting short-term memory contexts. Currently, only leaks in expressions executed as quals or projections are handled. Clean up some old dead cruft in executor while at it --- unused fields in state nodes, that sort of thing. 2000-07-12 04:37:39 +02:00			`extern void ExecSetParamPlan(SubPlan node, ExprContext econtext);`
Subselects... 1998-02-13 04:46:56 +01:00			`extern void ExecEndSubPlan(SubPlan *node);`
Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 07:26:15 +01:00
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 18:46:40 +01:00			`#endif /* NODESUBPLAN_H */`
