pg_advance_replication_slots can advance uninitialized physical
slots and that might not be good. (Logical slots always have
initial invalid values in thw two lsn columns.)
About scanning from restart_lsn in the advancing function, I
think I confirmed that the value always comes from
XLogRecordBuffer.origptr, which comes from ReadRecPtr, not
EndRecPtr, which cannot be on page boundary.
FWIW, as the result, it looks fine for me also regarding the
issue on this thread.
regards.
