Hello,

I'm trying to write a program that speaks the streaming replication protocol (for logical decoding).  I get to the part where I issue a query:

START_REPLICATION SLOT regression_slot LOGICAL 0/0;

And after that, I receive an empty copy_both_response then a copy_data that has a "Primary keepalive message" in it.  Then I'm stuck; I don't know how to respond to that.

I'm going off the documentation here:


Which I find really confusing and hard to understand.  Any help would be appreciated!  Thank you.
