failed deparser AST

[salisbury-espinosa]

const result = parseQuerySync(`select from test_table WHERE status = 'complete'::text`);
const stmts = result.stmts.map(mapStmt);
deparse(stmts, {})

=>

deparser/deparser.ts:720
    if (node.val.String) {
                 ^
TypeError: Cannot read properties of undefined (reading 'String')

after fix:
https://github.com/launchql/pgsql-parser/blob/main/packages/deparser/src/deparser.ts#L720

if (node.val.String) { => if (node?.val?.String) {

result is

SELECT FROM test_table WHERE   null::undefined

[salisbury-espinosa]

select from test_table WHERE status = 'complete'

after pipeline (parseQuerySync |> deparse) result is

SELECT FROM test_table WHERE

without status = 'complete'
