Dropping a loadable library - Mailing list pgsql-admin

Hi all,

My efforts with pg_upgrade have hit a new, what should be easy solve, problem. It failed due to a loadable library
beingpresent in 9.3.3 that I really don't need any longer. My  
problem is, how do I drop a library from the 9.3.3 instance? I've done some internet searching, but haven't found
anythinguseful. 

Anyone?
