SYNOPSIS
check_group_min_max_predicates()
cond tree (or subtree) describing all or part of the WHERE
clause being analyzed
min_max_arg_item the field referenced by the MIN/MAX function(s)
min_max_arg_part the keypart of the MIN/MAX argument if any
cond [in] the expression tree being analyzed
min_max_arg [in] the field referenced by the MIN/MAX function(s)
image_type [in]
has_min_max_arg [out] true if the subtree being analyzed references min_max_arg
has_other_arg [out] true if the subtree being analyzed references a column
other min_max_arg
DESCRIPTION
The function walks recursively over the cond tree representing a WHERE
clause, and checks condition (SA3) - if a field is referenced by a MIN/MAX
aggregate function, it is referenced only by one of the following
predicates: {=, !=, <, <=, >, >=, between, is null, is not null}.
predicates $FUNC$:
{=, !=, <, <=, >, >=, between, is [not] null, multiple equal}.
In addition the function checks that the WHERE condition is equivalent to
"cond1 AND cond2" where :
cond1 - does not use min_max_column at all.
cond2 - is an AND/OR tree with leaves in form
"$FUNC$(min_max_column[, const])".
RETURN
TRUE if cond passes the test
