Not working with large SQL : Error: Connection terminated unexpectedly

I’m trying to query a large SQL file (~65000 lines) and constantly getting Error: Connection terminated unexpectedly after 2 min of execution.

Here is code:

'use strict';

var fs = require('fs'),
    pg = require('pg'),
    Pool = pg.Pool;

(async () => {
    var pool = new Pool({
        database: 'some database',
        user: 'app',
        password: 'some password',
        host: 'some host',
        port: 9999,
        ssl: true,
        max: 20, // set pool max size to 20
        min: 4, // set min pool size to 4
        idleTimeoutMillis: 10000, // close idle clients after 1 second
        connectionTimeoutMillis: 10000, // return an error after 1 second if connection could not be established
    });

    var client = await pool.connect();

    pool.on('error', error => {
        console.error('error event on pool (%s)', error);
    });

    try {
        await client.query('BEGIN');


        const queryText = fs.readFileSync('./v2-game_data.sql') + '';


        const res = await client.query(queryText)


        await client.query('COMMIT')

    } catch (e) {
        await client.query('ROLLBACK')
        throw e
    } finally {
        client.release();
    }
})();

And here is error:

events.js:174
      throw er; // Unhandled 'error' event
      ^

UPD

With pg-native the error is:

events.js:174
      throw er; // Unhandled 'error' event
      ^

Error: SSL SYSCALL error: EOF detected

How to make it work?

I really believe that there is a vast amount of other methods of doing this job. And I can understand if it’s pointless for you, but it doesn’t mean that it pointless for me. I have tasks and they have to be accomplished in exact way. So my answer will be like because of reasons

If the SQL file contains basic DML commands (ex: INSERT, UPDATE, etc) then unless you hit some kind of memory issue in node, it should work fine.

If the SQL file contains COPY commands with inline data this will not work. The COPY protocol requires special handling and changes the client protocol handlers to expect a copy data stream.
