chunk size problem

I started getting these error messages

webunl=> \dt
NOTICE: AllocSetFree: detected write past chunk end in
TransactionCommandContext 3a4608 pqReadData() -- backend closed the channel
unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost.
Attempting reset: Failed.

The logs on the first times today I had these problems said this:

Any idea? Some databases are screwed up

Porqué usar una base de datos relacional cualquiera,
si podés usar PostgreSQL?
