I am encountering an intermittent NullPointerException when I call
connection.getMetaData().getUDTs(). I traced it to a null key in
TypeInfoCache._pgNameToSQLType, inserted by a previous call to
connection.getMetaData().getTypeInfo(), as a result of a lingering
temporary table.
I attached a basic reproducer. For me it usually fails on the second or
third time through the loop.
I am using the latest driver (9.3-1101-jdbc41), and I get the same
results running against 9.2 and 9.3 servers.
