Are there any pitfalls in using Doctrine with PostgreSQL in Symfony?

We are starting a new Symfony project and we made the decision (based on performance tests, load tests) to use Doctrine ORM with PostgreSQL instead of MySQL / MariaDB.

MySQL is the preferred DB choice for Symfony projects ( [symfony] [mysql] , [symfony] [postgresql] ), so choosing PostgreSQL is a rare decision, and there may be some pitfalls we should look at.

The question is, does Symfony Doctrine ORM support PostgreSQL integration as well as MySQL?
