strange error message

Hi,

I've got a strange error message in our java application.
the only reference to this message i find in
http://mingo.info-science.uiowa.edu/eichmann/courses/database/Postgres/programmer.pdf<https://webmaileu.harman.com/owa/redir.aspx?C=834176e3ff1b4f1eae758f541e93549f&URL=http%3a%2f%2fmingo.info-science.uiowa.edu%2feichmann%2fcourses%2fdatabase%2fPostgres%2fprogrammer.pdf>.
but I still don't know how to solve this or even what the source od this
error is.
currently I don't have the executed sql yet. I'm trying to get this.
Any Idea what that could be?
