Boa tarde pessoal, estou com um problema sério em um dos meus clientes.
Há 300 máquinas conectadas (em torno de 2 conexões por máquina) no servidor
postgres e o servidor está com o processor a 100% de uso e memória com
1900gb em uso e está MUITO LENTO.
Se alguém puder me ajudar eu agradeço.
A configuraçào do meu postgre.conf está assim:

# connection slot, plus lock space (see max_locks_per_transaction). You
# might also need to raise shared_buffers to support more connections.
