Speculare PGCDC is used to stream change from the Postgres database over WebSocket to active clients.
As of now Speculare PGCDC does not provide easy setup solution such as a one-line installer (but it's planned). The current recommanded way to install Speculare PGCDC is to build it from source. But don't be afraid, it's easy and straightforwards.
Speculare PGCDC is a Rust project that rely on some dependencies to be able to be built correctly. Much of them are default deps in most servers.
