I think it is asking for trouble in general to use the DDL from one 
version of pgcrypto with a different version of the pgcrypto 
implementation. However, you're right that people are inevitably going 
to do this, so I suppose we need to keep the checks. Perhaps it would be 
worth adding something to the installation documentation suggesting that 
people take care when installing new versions of contrib/ packages and 
the like without updating the DDL for those packages.
