This looks like you are using a 9.3.5 build of plpgsql.so with a server
that is 9.3.4 or older.
The most likely explanation of that is that you upgraded a 9.3.x
installation to 9.3.5 but neglected to actually restart the server.
"select version();" would help confirm what server version is running.
