I tried turning off ssl renegotiation by setting "ssl_renegotiation_limit = 0" in postgresql.conf but it had no effect.
Theparallel dump still fails on large tables consistently.
Thanks

I'm wondering about SSL renegotiation failures as a possible cause of the disconnect --- that would explain why it only
happenson large tables.
