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:
