Обсуждение: bug in jdbc

Marek-

This appears to be a normal message from the driver reporting an error in
the submitted SQL statement. The "Something unusual" part of the message is
a bit misleading, but the rest of the message points pretty clearly to a
problem with the function pg_encoding_to_char. What happens if you try to
execute the same statement via psql?

jdbc7.0-1.2 driver working OK

there is exception :

 Something unusual has occured to cause the driver to fail. Please report
this exception: Exception: java.sql.SQLException: ERROR:  No such function
'pg_encoding_to_char' with the specified attributes

Stack Trace:

I think this is a case of using the jdbc 1.1 driver in a 1.2
environment? There are similiar messages in the archive

This sounds better than my idea- Try Dave's solution before mine.
