"cache lookup failed" certainly smells like a server internal error, but we'd have heard about it if the trivial case you show could reach such a problem. I'm thinking there's things you haven't told us. What extensions do you have installed? Maybe an event trigger? Also, the reference to ENCODING 'ISO-8859-1' makes me wonder what encoding conversion is being performed. regards, tom lane
