I struggle now for some days. I not able to find a simple reproducer, a reduced version. Kind of one statement, second statement and ..  voila. But without success.
That's why I started to debug. Looks like the problem is in the class org.postgresql.jdbc.TypeInfoCache. It has sth. to do with overwriting in the HashMaps of the TypeInfoClass if an type is used as an Array and as well as not as an Array.

I added a lot Log-Statements to TypeInfoClass. But is hard for me to follow, what triggers the Type-Queries to the database. 

I could export the DataBase and checkin my Project (github) and explain how to reproduce the error.

@davecramer what do you think, or can we chat
