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.

Can you send us a reproducable example? That would be great. I assume
this is 6.3.2.
