That library is great but pretty dated. I put together WalEx which borrowed a good bit from Cainophole but uses the new WAL listening logic in Postgrex:
What is dated? WalEx is still using logical replication slots, right? Trying to bring myself up to speed. Currently am using cainophile and would like to understand what WalEx is offering above and beyond. Cainophile isn't actively maintained but I think that's because it is feature complete, at least according to the author's concerns.
That is interesting. So this would mean using what I already have when using Ecto instead of the other postgres client I think cainophile uses.sounds good to me.
