Using Drupal, MySQL (or MariaDB) simply works much smoother than PostGres. That is because apparently Drupal has been designed around MySQL. You may be quite sure that if you are having a problem with Drupal on PostGres, that the same problem doesn't exist when using MySQL. In 2011, we started out using Drupal with PostGres. After a year or two, we migrated to MySQL. I think it's likely that the situation is quite similar with WordPress.
