Evidently a connectivity problem, not a database integrity problem.
Is pg_dump running on a different machine than the server? If so
you could be looking at network hardware issues.
Is pg_dump using an SSL-encrypted connection? If so maybe it's a
renegotiation problem. Try setting ssl_renegotiation_limit = 0
in the server's configuration.
