    .cond_where(
        Expr::col((Glyph::Table, Glyph::Image))
            .eq(Expr::col((Char::Table, Char::UserData))),
    )
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"UPDATE "glyph" SET "tokens" = "character"."character" FROM "character" WHERE "glyph"."image" = "character"."user_data""#
);
assert_eq!(

use sea_query::extension::postgres::PostgresSelectStatementExt;

let query = Query::select()
    .columns([Glyph::Image])
    .from(Glyph::Table)
    .table_sample(SampleMethod::SYSTEM, 50.0, None)
    .to_owned();

assert_eq!(

            .using(Expr::col(Char::Id).cast_as(Alias::new("integer"))),
    )
    .to_owned();

assert_eq!(
