ALTER TABLE RENAME and primary key

[brian <brian@xxxxxxxxxxxxxxxx>]

I'd like to rename a table but am unsure how this will affect the 
primary key. That is, the table currently being named 'service', it has 
a pkey named 'service_id_pkey'. I'd like to change the table name to 
'service_provider' (which would mean i'd get 'service_provider_id_pkey').

There's a second table that has a foreign key constraint on 
service_id_pkey, so do i need to drop that constraint first, rename the 
first table, then re-create the constraint using the new pkey name?
