af2a0dfd65 Describe the date/time parsing rules. 
Include specific information on the supported time zones.
 It's a really big table, so maybe it should go into an appendix instead.

ba8808b2a6 Substitute great info from Stefan Simkovics' Master's Thesis. 
Still need to add some acknowledgements at the top of the doc;
 already have full info in the bibliography but since the original is
 being spread across the existing docs we should also mention things
 locally.

07c33ba79e pg_dump -d or -D didn't quote special characters in INSERT data 
correctly.  -D had problems with tables with inherited fields, also.

566c712c58 Revert some changes from the INTERSECT/EXPECT patch that broke 
rule system semantics by having Var nodes referenced across multiple
parsetrees when rules split them.

Added more tests to the rules regression test.

The code in question resulted from v6.3 based development and was
a little careless applied to the v6.5 source tree.

28fc5d7b83 Reenabled parentheses for grouping multiple rule actions and 
added this syntax to rules regression test so it will show up
if someone breaks it again.

ef590e101e Changed ExecConstraints() and ExecRelCheck() to cache the constraints 
qualification expression trees in the execution state. Prevents from
memory exhaustion on INSERT, UPDATE or COPY to tables that have CHECK
constraints. Speedup against the variant using freeObject() is more than
factor 2.

48fd9a2cc2 Add equality checking for T_Query so that we don't get 
complaints in UNION regress test.  Probably still need some more node
types to be handled here, but I'm done for the day...
