[ic] FATAL 1: my bits moved right off the end of the world!

Vrs,: IC 4.8

I'm getting this message when adding information to my products through the
Admin window.

Can anyone tell me why, because the 'probable meaning' doesn't help?

=====================================
Sorry, there was an error in processing this form action. Please report the
error or try again later. (DBD::Pg::st execute failed: FATAL 1: my bits
moved right off the end of the world! Recreate index products_description.
pqReadData() -- backend closed the channel unexpectedly. This probably means
the backend terminated abnormally before or while processing the request. )
=====================================

Thanks, Greg
