Installing with libs of postgresql-libs

Hi list,

Could someone tell me what libs are packed in the rpm 
below ?
postgresql-libs-8.2.3-1PGDG.i686.rpm

We are concerned about the problem of compatibility with 
Oracle and we prefer to check all the libs to not put the 
Oracle system down.

I think it is just a metter of rpm -qa 
postgresql-libs-8.2.3-1PGDG.i686.rpm but I do not have the 
adm permissions. 

Any help would be glad
