Hello Gary, 

the problem with this change is that it is not backwards compatible. Though the question is, why somebody would like to keep a not deterministic behavior of the current code.

And if you are fixing this, probably it would make sense to fix getSQLType() as well.

Also it can fill your server logs with errors, if the type does not exist, regtype cast will throw an ERROR

I have prepared a little bit different change: https://github.com/pgjdbc/pgjdbc/pull/52
  
Cheers,

-- Valentine

I found that type cache info wasn't honoring search path.  (I had a
UDT type that shared a name with a table).

This fixed it.
