PostgreSQL: full text search on entire words

Here is a way I found to make full a full text search on entire words only with postgreSQL (tested on v8.1):

select field1,field2 from my_table
where field1 similar to '[[:&lt;:]]myword[[:&gt;:]]'

1 2	select field1,field2 from my_table where field1 similar to '[[:<:]]myword[[:>:]]'

SQL entire word, full text, postgres, search, sql
