Docker Laravel PostgreSQL - QueryException: could not find driver - php

Question

I've been trying to run my new REST api calls but i get this error on postman:
Illuminate\Database\QueryException: could not find driver (SQL: insert into "companies" ("name", "establishment", "updated_at", "created_at") values (Tekmon, 2021-08-10, 2021-08-31 19:29:31, 2021-08-31 19:29:31) returning "id") in file /var/www/vendor/laravel/framework/src/Illuminate/Database/Connection.php on line 671
I have succesfully run my migrations to create the database tables.
phpinfo on docker container does not have pdo_pgsql extension on the list.

I've searched many questions for some hours now but nothing worked.
Thanks.

As Sammitch below mentioned, and a video on YouTube by BPKodes, I needed to rebuild the container, which I didn't in the beginning, with libpq-dev instead of postgresql-dev. Hope this helps anyone.
