PG::Error: SSL SYSCALL error: EOF detected

When i do my first SELECT requests to my RoR app i get "PG::Error: SSL SYSCALL error: EOF detected". What should i do to turn off SSL in my Postgresql?

Error info:

ActiveRecord::StatementInvalid: PG::Error: SSL SYSCALL error: EOF detected : SELECT "vacancies".* FROM "vacancies" WHERE (moderated_at IS NOT null) ORDER BY id DESC LIMIT 10
