Tom Lane b153c09209 Add a bunch of new error location reports to parse-analysis error messages. 
There are still some weak spots around JOIN USING and relation alias lists,
but most errors reported within backend/parser/ now have locations.

Tom Lane 595ed2a855 Make the behavior of HAVING without GROUP BY conform to the SQL spec. 
Formerly, if such a clause contained no aggregate functions we mistakenly
treated it as equivalent to WHERE.  Per spec it must cause the query to
be treated as a grouped query of a single group, the same as appearance
of aggregate functions would do.  Also, the HAVING filter must execute
after aggregate function computation even if it itself contains no
aggregate functions.

Tom Lane 5ea214b590 It seems some case-insensitive locales sort upper case before lower 
(BBBB before bbbb) and others the other way around.  Provide comparison
files that cater to both approaches.
