Huh? Are you thinking of the "Record-based Log Shipping" described in
the manual, using a program to poll pg_xlogfile_name_offset() in a tight
loop, as a replacement for streaming replication? First of all, that
requires a big chunk of custom development, so it's a bit of a stretch
to say we have it already. Secondly, with that method, the standby stillstill be replaying the WAL one file at a time,
whichmakes a difference
 
with Hot Standby.
