Error Message

I hate to bother you developers, but I have a question about the
Postgres server.  Can someone explain to me the following error messages
and how I can avoid them?  I recieved when trying to select from a
simple table with about 5 rows.  When there were only two rows in the
table, the select came back ok, however when I then inerserted 3 more
rows, I started to see this message.  Thank You.
