Hi, all
In Stream Replication Protocol [1], the documentation of `START_REPLICATION` message is
XLogData (B)
…
Primary keepalive message (B)
…
Standby status update (F)
…
Hot Standby feedback message (F)
...
I’m confused about the means of ‘B’ and ‘F’? If it doesn't make sense, why we document here?
However, if it makes sense, should we explain it?
Can someone help me out?
Anyway, thanks in advance!
