Bug fixes

• Fix arguments when nesting custom expressions #333
• Fix clippy warnings for manual map #337

Breaking Changes

• Introducing a dedicated ReturningClause instead of reusing Select on returning: #317

.returning(Query::select().column(Glyph::Id).take()) // before
.returning(Query::returning().columns([Glyph::Id])) // now

• In #333, the custom expression API changed for Postgres, users should change their placeholder from ? to Postgres's $N

let query = Query::select()
    .columns([Char::Character, Char::SizeW, Char::SizeH])
    .from(Char::Table)
    .and_where(Expr::col(Char::Id).eq(1))
    .and_where(Expr::cust_with_values("6 = $2 * $1", vec![3, 2]).into())
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT "character", "size_w", "size_h" FROM "character" WHERE "id" = 1 AND 6 = 2 * 3"#
);

As a side effect, ?? is no longer needed for escaping ?

let query = Query::select()
    .expr(Expr::cust_with_values(
        "data @? ($1::JSONPATH)",
        vec!["hello"],
    ))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT data @? ('hello'::JSONPATH)"#
);

• In #314, ColumnType's Binary(Option<u32>) changed to Binary(BlobSize), so if you used Binary(None) before, you should change to Binary(BlobSize::Blob(None))
