obtaining ARRAY position for a given match - Mailing list pgsql-general

Hi,

I'm trying to get the array position for a given match as thus:

This gets me the record for a given match:
SELECT *  FROM garmin_units WHERE 'L' = ANY (protocol_tag);

Ok. so far so good...
But what about getting the array position at which 'L' is stored?

Searching the Postgresql docs gives me no answer... :(
Am I on a wild goose chase?

Any insight highly appreciated ;)

BR,
Pedro Doria Meunier.
