Hi,
 I'd like to know if the values of postgres's Oids can changes its values for the same object. I want to use them in my
aplication,but I'm afraid they could change and I get errors. 

I use the field Oid of table pg_type to identify the type of a field in a query. It could bring me errors in the
future?For example, the  oid value associated to type int4 could change at any future time? 

Regards,
Yadira
