Greater than a value

I have the following query:

select count(*),msg_text from msg_table where msg_text like '%PIX-1%'
group by msg_text order by count desc;

And I qould like to be able to do something like:

select count(*),msg_text from msg_table where msg_text like '%PIX-1%'
COUNT => '50' group by msg_text order by count desc;

Is that possible in PostgreSQL?
