The patch implements MySQL parsing and round-tripping for `CAST(... AS <type> ARRAY)` by consuming the trailing `ARRAY` and preserving it in the AST/display path (via a `DataType::Array(TypeSuffix(...))` representation). This differs structurally from the gold patch (which uses an `Expr::Cast` flag), but it satisfies the intended functional change.
Code Review
The patch likely passes visible tests and supports MySQL CAST ARRAY cases, but it only enables the syntax behind a MySQL dialect gate and uses a broader datatype-level representation that diverges from the intended cast-local approach.
The parser only accepts `... ARRAY` in CAST when `supports_cast_array_suffix()` is true, so the same SQL fails under generic/non-MySQL dialects even though the intended parser change is syntax-level support for this CAST form.
Representing `CAST(... AS type ARRAY)` as `DataType::Array(ArrayElemTypeDef::TypeSuffix(...))` conflates CAST syntax with datatype semantics and adds a new global type form that is not intrinsically a datatype in this context.
