PostgreSQL adapter can't use smallserial type

[badmansan]

$smallSerial = (new \Phinx\Db\Table\Column())->setName('id')
	->setType(\Phinx\Db\Adapter\AdapterInterface::PHINX_TYPE_SMALL_INTEGER)
	->setIdentity(TRUE);

$this->table('test', ['id' => FALSE, 'primary_key' => ['id']])
	->addColumn($smallSerial)
	->create();

The result table contains column id with type integer instead smallint.
This is because of this code:

$buffer[] = $column->getType() == 'biginteger' ? 'BIGSERIAL' : 'SERIAL';

Can any one fix this?

Why are you not using normal integers?
Are u able to make a pr here?

Why are you not using normal integers?

My reference table is very small, but related table is very large.

Are u able to make a pr here?

Sure, here

My tip for you: Don't nano-optimize.
It only creates problems without any benefit for you.
In this case you also don't gain anything.
