pub const VARCHAR: TypeMarker;Expand description
Specifies a VARCHAR column type.
VARCHAR stores variable-length character strings.
In PostgreSQL, VARCHAR without length limit is equivalent to TEXT.
Use #[column(VARCHAR(255))] to preserve a bounded physical column while
keeping the Rust field type as String; Vec<String> preserves the same
bound for each array element.
