Psalm 7

The mismatch is deliberate.

This part of the code is too convoluted for Psalm (and maybe for humans
too).

That method is already defined in the parent interface.

This was shown as an error by Psalm but should not be considered one
IMO. See https://github.com/vimeo/psalm/pull/3203

Merge release 2.10.2 into 2.11.x

Sync expected coverage report count

See e360ba05 for AppVeyor. For ContinuousPHP, I am not how to track the
history of the pipeline, or if there is one.

Stop relying on the master version of Psalm

Mark every exception as immutable

I just got bitten by a bug on master at
https://github.com/doctrine/sql-formatter/pull/43#issuecomment-615576443,
and there are good chances we have the bug on the Dbal too. Anyway, it
only makes sense to use the same version as in the vendors.

Reworked LoggingTest to be able to test Statement::executeUpdate()

Remove baseline

null contradicts the phpdoc

For some reason a low version crashes Psalm.
