Summary
#33 and version 2.11.1 introduced better checking for PDO::FETCH_* constants but marked the constant PDO::FETCH_COLUMN as invalid and commented it out. I guess this was done based on this comment: zendframework/zend-db#296 (comment)
I can't find any reason why it should be invalid in the documentation. And based on some research it should be supported by all PDO drivers.
I've also tested if and it returns an array where the values are the value from the selected field for each row. So it should work as expected (only tested with MySQL).
Previous behavior
PDO::FETCH_COLUMN was an valid fetch mode.
Current behavior
Laminas\Db\Adapter\Driver\Pdo\Result throws an exception when PDO::FETCH_COLUMN is used.
How to reproduce
Use any query and set fetch mode to PDO::FETCH_COLUMN.
