Now that we have set archiver messages to DEBUG levels, there's no easy
way of seeing what file we are currently working on.
The behaviour of the startup process and archiver should be symmetrical,
allowing it to be used for replication monitoring.
Before archive_command
postgres: archiver process archiving 00000001000000000000000B
After archive_command
postgres: archiver process archived 00000001000000000000000B
patch posted to -patches, intended for 8.3
