[BUG]: Do not know how to serialize a BigInt

[AntonOfTheWoods]

Describe the bug
When arrays are passed as parameters to the query function, the "dumb" version of the JSON.stringify is used, and this fails for BigInts.

To Reproduce - include code sample(s)

  const pg = await PGlite.create();
  const myint = [{ id: 1 }, { id: 2 }];
  const mybigint = [{ id: 1n }, { id: 2n }];
  await pg.exec(`CREATE TABLE IF NOT EXISTS "myint" ("id" int NOT NULL);`);
  await pg.exec(`CREATE TABLE IF NOT EXISTS "mybigint" ("id" bigint NOT NULL);`);
  await pg.query(`INSERT INTO myint (id) SELECT x.* from json_to_recordset($1) as x(id int); `, [myint]);
  console.log("got", await pg.query("SELECT * FROM myint"));
  // the following line fails
  await pg.query(`INSERT INTO mybigint (id) SELECT x.* from json_to_recordset($1) as x(id bigint); `, [mybigint]);
  console.log("got", await pg.query("SELECT * FROM mybigint"));

Logs

Details

• PGlite version: 0.3.15

Additional context
This also affects the json initial insert mode for pglite-sync

Try

BigInt.prototype.toJSON = function() {
    return this.toString()
}
