how to close underlying connection pool being used by drizzle?

test.before(async t => {
    t.timeout(30000, 'waiting for the database to be ready')
    const initScript = resolve(__dirname, '..', '..', 'infrastructure', 'dev-schema.sql');
    // @ts-ignore
    t.context.pg = await new PostgreSqlContainer()
        .withBindMounts([{
            source: initScript,
            target: '/docker-entrypoint-initdb.d/init.sql',
        }])
        .start();
    // @ts-ignore
    t.context.db = await prepareDb(t.context.pg.getConnectionUri())
    // @ts-ignore
    t.context.server = await prepareServer(t.context.db)
})

test.after.always(async t => {
    try {
        // @ts-ignore
        await t.context.pg.stop({timeout: 500})
    } catch (e) {
        // swallow for now
    }
})
