getting at sequence previous/next values

От

Hello,

I've got a table that looks basically like:
id_show         | serialshow_name       | text show_type       | text                        created_on      |
timestampwithout time zone 
 

When looking at a row with an id_show of value n, I'd like to have an 
easy way of knowing the preceding and next values of id_show in the 
sequence (which might have holes).

Is there some convenient way to get that info, or must I do a full-blown 
select?

Thanks,
