I'm looking into adding sql standard aggregates EVERY/ANY/SOME.
It seems to me that there is a syntax ambiguity with ANY and SOME:
CREATE TABLE bla(b BOOL);SELECT TRUE = ANY(b) FROM bla;
Is parsed as an array-operator and there is a semantical error because no
array is provided. Now ANY could be an aggregate function call, and it
should be fine.
However I really cannot see (my usual lack of imagination) how to handle
this from the parser.
Thus I'm afraid that I'll have to rewrite the A_Expr structure into a
FuncCall to 'any' or 'some' somewhere.
Comments? Any better idea?
