Lack of documentation on serialization of custom Javascript

[UsamaButt1593]

Parsing Postgres types is well documented on node-pg-types like to parse every TIMESTAMPZ type into a Moment object, we can do something like:

var types = require('pg').types
var moment = require('moment')
var parseFn = function(val) {
   return val === null ? null : moment(val)
}
types.setTypeParser(types.builtins.TIMESTAMPTZ, parseFn)

But there is complete lack when it comes behaviour of library while serializing Javascript objects used as values inside pool.query or client.query method.

For example, if i pass a Moment object, how is it serialized? Is it done by calling Moment#toString() method? What if a library user wants to describe custom srialization behaviour? As I want to use Moment#toISOString() whenever a Moment object is passed to query.

Lets consider an example:

CREATE TABLE IF NOT EXISTS RefreshToken (
	id SERIAL PRIMARY KEY NOT NULL,
	token TEXT NOT NULL,
	expires_at TIMESTAMPTZ NOT NULL
);

import moment from 'moment';

const token = "xxxxx.yyyyy.zzzzz";
const expires_at = moment().add(1, 'days'); // local time zone

const result = await pool.query({
    text: 'INSERT INTO RefreshToken(token, expires_at) VALUES ($1, $2)',
    values: [
        token,
        expires_at.toISOString() // I want ISO-8601 UTC timestamp to be passed to Postgres. But it is so easy to forget to call toISOString on every query.
     ],
  });

Is there any thing like require('pg').types.setTypeSerializer(Moment /* Javascript Type*/, serializeFn)???

Thanks much. I realize that it is indeed mentioned in the docs.
