template1 as default database for PostgreSQL

Pgsql connection test with charset parameter

fix incorrect ordering of columns in clustered indexes on sql server

Fix test failures on windows due to differing newlines

The bin/doctrine-dbal.php file is not an executable file. Adding them as a bin in composer.json means that any composer install will trigger changes in the source when using symlinks because of the chmod. This makes things a pain when installing from source.
Thus, there is no valid reason to add it. It is absolutely not necessary when using a composer install. The issue requesting it previously is actually an issue in Laravel which replaces the proxy file/symlink generated by Composer with a copy of the original file, which of course cannot work because of paths used in require. But copying a second file does not help for that (unless in very specific cases). It only moves the issue until the next require call.
