function DatabaseTasks_pgsql::checkPHPVersion in Drupal 7

Check PHP version.

There are two bugs in PDO_pgsql affecting Drupal:

• in versions < 5.2.7, PDO_pgsql refuses to insert an empty string into a NOT NULL BLOB column. See: http://bugs.php.net/bug.php?id=46249
• in versions < 5.2.11 and < 5.3.1 that prevents inserting integer values into numeric columns that exceed the PHP_INT_MAX value. See: http://bugs.php.net/bug.php?id=48924
