Postgresql packages in Solaris

All,

I received this question from a customer yesterday (below), and unfortunately I do not have the answer.  Please let us know if you know the answer, it would be greatly appreciated...
 
"What we are trying to figure out is if removing the packages SUNWpostgr-83-devel, SUNWpostgr-83-pl, SUNWpostgr-devel, SUNWpostgr-pl will cause any harm to our systems. For example, in the PDF that you sent yesterday, it states that package SUNWpostgr-pl is part of the core server package. 

I am not sure as to what the core server package is, but when you try to remove those packages from prodreg it gives about 2 or 3 warnings on the performing the action. 

Just to be on the cautious side, we want to verify that removing those packages will not have any negative impact on our systems. The reasons behind wanting to perform these actions are CVE-2010-1169, CVE-2010-1170, and CVE-2010-1447."


Thank You,
Paul
