regexp searching in arrays not working?

["Rhys Stewart" <rhys.stewart@xxxxxxxxx>]

Hi all, 
have a column which is of type text[]. the following works:

       select * from table where 'Transformer' = ANY (thiscol)

this also works 
   
        select * from table where 'Transformer' ~ ANY (thiscol)

however if i have a partial string like so

         select * from table where 'Trans' ~ ANY (thiscol)

it returns nothing. 

Is regex searching not functioning (as i expect it to?) i searched the docs and didnt see anything about it.



Regards

Rhys
