object tracking

Hi,

I have a fairly large data warehouse in Greenplum, and am having trouble tracking object changes. 

I need to

1.        Know when an object was changed, by who.

2.       Have some logging about when an object was dropped – especially drop cascade.

Currently I’m having a problem with a set of disappearing views.   We’re still in pre-prod environment, but

Any suggestions?

I’d like  

1.        PG to timestamp the catalog tables

2.       Permit triggers on catalog objects.
