The error that occurs is:
Fatal error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY' in /www/drupalhead/includes/database/mysql/database.inc on line 31

This same instance of drush works perfectly on my localhost d6 and d5 sites, so I assume we're just chasing head here, but I wanted to report it anyway for sanity's sake. :)

I'm receiving the same message running drush update on 7.x-dev. Elsewhere in the world, PHPers were complaining about it: http://bugs.php.net/bug.php?id=47224

I'm not savvy enough to handle this one personally.

drush is not d7 compatible for the most part. and anyway, db updates from head to head are not supported by drupal.

I got the same error with the latest CVS version while using simpleTest:

$ /usr/bin/php ./scripts/run-tests.sh --url http://localhost:8888/drupal-cvs/ --clean

Fatal error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY' in /Applications/MAMP/htdocs/drupal-cvs/includes/database/mysql/database.inc on line 31

I had the same problem on Mac OS using MAMP when I tried to run the run-test.sh on D7 like in #4. The problem was simply due to a bad version of PHP. Using the MAMP php binary works:

/Applications/MAMP/bin/php5/bin/php ./scripts/run-tests.sh

hope that helps.

To get d7's installer going edit /Applications/MAMP/conf/php5/php.ini and uncomment the pdo_mysql extension to get MySQL running.

On FreeBSD, you need to install the pdo_mysql module on top of your PHP installation:

portmaster databases/php5-pdo_mysql

or

cd /usr/ports/databases/php5-pdo_mysql; make install;

If you haven't already installed mbstring do that too: portmaster converters/php5-mbstring

The ports automatically edit your php/extensions.ini file for you.

Restart your webserver, then start the installation.

works if php_pdo_mysql is enabled. You can do this by uncommenting extension=php_pdo_mysql.dll in php.ini and restarting apache

Received the same error on linux (Ubuntu 10.10), solution was to install php5-mysql . Note that /etc/php5/conf.d/pdo.ini already enabled the pdo option.
