Cleanup up include files. 1997-11-25 20:14:33 -05:00			`#include "nodes/plannodes.h"`

Clean up handling of variable-free qual clauses. System now does the right thing with variable-free clauses that contain noncachable functions, such as 'WHERE random() < 0.5' --- these are evaluated once per potential output tuple. Expressions that contain only Params are now candidates to be indexscan quals --- for example, 'var = ($1 + 1)' can now be indexed. Cope with RelabelType nodes atop potential indexscan variables --- this oversight prevents 7.0.* from recognizing some potentially indexscanable situations. 2000-08-12 22:50:35 -04:00			`extern TupleTableSlot ExecNestLoop(NestLoop node);`
Used modified version of indent that understands over 100 typedefs. 1997-09-08 17:56:23 -04:00			`extern bool ExecInitNestLoop(NestLoop node, EState estate, Plan *parent);`

Optimizer cleanup. 1999-02-12 12:25:05 -05:00			`extern void ExecReScanNestLoop(NestLoop node, ExprContext exprCtxt,`
pgindent run over code. 1999-05-25 12:15:34 -04:00			`Plan *parent);`
OK, folks, here is the pgindent output. 1998-09-01 00:40:42 -04:00			`#endif /* NODENESTLOOP_H */`
