When I upgraded from postgresql 9.6 to 10, the postgres server failed to start. Error message: 'max_wal_senders must be less than max_connections'. The configuration file /etc/postgresql/10/main/postgresql.conf has the line
#max_wal_senders = 0 suggesting that 0 is a default value. When I removed the comment symbol, effectively including this setting, I could start the server. This is different from 9.6. Is this a known problem, or should I report it as a bug? Simon
