Re: remaining sql/json patches

two cosmetic minor issues.

+ * using coerce_type() or OMIT QUOTES is specified for JSON_QUERY.  If the

+typedef struct JsonCoercion

+ int32 targettypmod;

comment:  'expr' may contain the cast expression;
here "exr" should be "cast_expr"?
"a SQL/JSON" should be " an SQL/JSON"?
