Hey,
To avoid creation of custom GiST-index you can use hstore,
which supports GiST and GIN indexes.
I propose you to add hstore column to the table and write trigger
function which will generate hstore from array on insert or update.
Or you can use hstore column instead of array.
Please, see

<nakagawa@ivp.co.jp>Thank you for your response.
Are there any technique to index that query for like search on Text[] Columns?
Thanks.
