< Int4 - limit >

Hey there,

 

(using postgres 6.5.0 - on Red Hat Linux)

 

I have built a small application which has a table for unique identifiers with a column of type int4.

 

This has one added to it each time a new key is required.  I am a little worried that at some point when the limit of int4 is reached the system will fall over.  Is this the case or is there a work around.

 

 

Thanks for any help.
