DELETE removes an entire row from your table.

You want to change the content of one column of an existing row in the table - for that you need to use UPDATE.

To remove a value from an array you the array_remove() function:

update test
   set name = array_remove(name, 'Jan')
where 'Jan' = any(name)

The where clause makes sure that only rows are updated that actually contain the value Jan in the array.
