d5e040b6f0 Add string_agg(X,Y) as an alias for group_concat(X,Y), for compatibility 
with SQLServer and PG.

6b6d6c6bd2 TK_IF_NULL_ROW expressions must be accumulated in the same way as TK_COLUMN 
expressions in an aggregate query.  Proposed fix for the problem identifyed by
dbsqlfuzz 8e17857db2c5a9294c975123ac807156a6559f13.

2c1b1ddc55 Do not attempt the OP_Count optimization on queries with HAVING clauses.

b9294de1e6 Allow a HAVING clause on any aggregate query, even if there is no GROUP BY 
clause.  This brings SQLite into closer agreement with PostgreSQL and fixes
the concern raised by 
[forum:/forumpost/1a7fea4651|forum post 1a7fea4651].

cd653a3266 Avoid deleting expression nodes in the flattener code, as they may be referenced by AggInfo objects further up the stack.

0c76e892d9 Apply the correct affinity transformations when pulling values off of the

6bab6f2b4d Disable the optimization where a REAL value with no fractional part 
is stored as an INTEGER when the integer uses as much space as the real
value it proposes to stand in for (8 bytes).  This avoids corner cases
of comparing integers against real values that are beyond the resolution
of an IEEE 754 double.  Fix for ticket [6c1d3febc00b22d457c78c2]

945498f3f2 Make sure that integer values are converted to real when pulled from 
a REAL table column by GROUP BY.  Ticket #2251.  Also make sure default
values are correctly expanded.  There may be other places in the code
where this issue comes up - we need to look further. (CVS 3659)
