ISTM anyone who thinks they need this actually need a full DDL log;
or at least, if we give them this, they will be back next week asking
for a full log.  So it'd save a lot of work to tell them to just log
their DDL to start with.

Some obvious objections to the simple approach:
- what if I want to know *who* made the change
- what if I need to know about the change before last
- what if I need to know about a DROP
- what if I need to know about operators, operator classes, schemas, etc etc
