Hi,
pg_current_wal_flush_lsn()pg_lsnGet current write-ahead log flush location
pg_current_wal_insert_lsn()pg_lsnGet current write-ahead log insert location
pg_current_wal_lsn()pg_lsnGet current write-ahead log write location
I guess write is about how many bytes written in shared cache, and
flush is flush to file, which makes it persistent.
Anybody gives some official explanation?
Thanks.
Regards,
