 This should signal a real error.  We've got an error system;
let's
 use it. 
O.K.

...
 The PostgreSQL error object should be encapsulated within the error
 data, so that a handler can use it. 
There is no real error object.  There is an errno-like string area
set aside in the PGconn object for the most recent backend error
message.[1]  It is not guaranteed to work, for various reasons.

that this is perhaps not the best mechanism in the world.
