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.

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