Fatal Error Running Drush 4.4 with Drupal 7.2 Do you have any idea on what might be causing this error in Drush w/ Drupal 7.2 (worked fine in Drupal 7.0)?


  Fatal error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY' in /path/to/includes/database/mysql/database.inc on line 42
  Drush command terminated abnormally due to an unrecoverable error.                                                                                                                    [error]
      Error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY' in /path/to/includes/database/mysql/database.inc, line 42


Line 42 of database.inc contains the following line: 

PDO::MYSQL_ATTR_USE_BUFFERED_QUERY =&gt; TRUE,


I thought this was related to PDO extension missing, but it is indeed installed. 

Here is the output of drush -v -d status:

EDIT:

phpinfo indicates that pdo, pdo_mysql are all installed. However, when I run 

pecl remote-info pdo (and pdo-mysql), I get a (among others): 


  Installed   - no -


So it appears that via the web requests, the extensions appear as installed, but not from the command line (same instance of php, v5.3). Is there a way to tell pecl what phpinfo already knows ... ?
Ok, another one for the "learning experience" column:

I specified

DRUSH_PHP=/path/to/php


right before this line in drush wrapper script:

if [ ! -z "$DRUSH_PHP" ] ; then


Works now.

Thanks @kiamlaluno &amp; @Berdir for your time and input. Hopefully this helps others.
