Tag appropriate files for rc3 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 ... 2004-12-31 17:04:05 -05:00			`* Portions Copyright (c) 1996-2005, PostgreSQL Global Development Group`

Revise nodeMergejoin in light of example provided by Guillaume Smet. When one side of the join has a NULL, we don't want to uselessly try to match it against every remaining tuple of the other side. While at it, rewrite the comparison machinery to avoid multiple evaluations of the left and right input expressions and to use a btree comparator where available, instead of double operator calls. Also revise the state machine to eliminate redundant comparisons and hopefully make it more readable too. 2005-05-13 17:20:16 -04:00			`* $PostgreSQL: pgsql/src/include/executor/execdefs.h,v 1.18 2005/05/13 21:20:16 tgl Exp $`

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 01:26:15 -05:00
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 12:46:40 -05:00			`#endif /* EXECDEFS_H */`
