Trouble connecting to PostgreSQL database.

When command php artisan migrate is ran, I get this error:

Illuminate\Database\QueryException 

could not find driver (SQL: select * from information_schema.tables where table_schema = public and table_name = migrations and table_type = 'BASE TABLE')

at vendor/laravel/framework/src/Illuminate/Database/Connection.php:671
  667|  // If an exception occurs when attempting to run a query, we'll format the error
  668|  // message to include the bindings with SQL, which will make this exception a
  669|  // lot more helpful to the developer instead of just the database's errors.
  670|  catch (Exception $e) {
> 671|      throw new QueryException(
  672|          $query, $this->prepareBindings($bindings), $e
  673|      );
  674|  }

This is my .env file:

DB_CONNECTION=pgsql
DB_HOST=host.docker.internal
DB_PORT=5432
DB_DATABASE=name
DB_USERNAME=user
DB_PASSWORD=secret

And checking phpinfo() within Laravel App, I can confirm that pgsql and pdo_pgsql extensions are installed.

Also by doing php -m inside docker CLI, both extensions are there.

Been on this error for some quite time and still can't figure out what's wrong. I hope someone can help me with this mess... :(

Edit: forgot to add my Dockerfile

FROM php:7.4-fpm

RUN apt-get update && apt-get install -y libpq-dev

RUN docker-php-ext-configure pgsql -with-pgsql=/usr/local/pgsql

RUN docker-php-ext-install pdo pdo_pgsql pgsql bcmath
