Some of the “method not found” errors originate from prophecy objects. I installed jangregor/phpstan-prophecy and phpstan/extension-installer, but then get the error:

- /home/travis/build/Beakerboy/drupal-project/vendor/phpstan/phpstan-deprecation-rules/rules.neon
- /home/travis/build/Beakerboy/drupal-project/vendor/mglaman/phpstan-drupal/extension.neon

It can lead to unexpected results. If you're using phpstan/extension-installer, make sure you have removed corresponding neon files from your project config file.

I have no neon file, and I do not see one in your project repository either.

It looks like many of the errors are due to limitations in the way the core doc blocks are used. The function Connection::schema() will always return a child of \Drupal\Core\Database\Schema, not this particular “abstract for all intents and purposes” class.

If I break the following statement

$result = $this->connection->schema()->customFunction();

Into

/** @var \Drupal\Driver\Database\module\Schema $schema */
$schema = $this->connection->schema();
$result = $schema->customFunction();

Then the error goes away. If you think this is the expected behavior, feel free to close it. Prophecy is still an issue though.
