Ok, I did the copy from pg_xlog directory into the restore.conf specifieddirectory. The standby servers seem fine with that, however, just copying does not inform the primary that
the copy has happened. The archive_status directory under pg_xlog on the primary still thinks the last WAL sent was *B7 and yet it's now writing *C9. When I did the copy it was
only up to *C7 and nothing else has shown in the standby's directory.
Now, the *.done files in archive_status are just zero length, but I'm a bit hesitant to just do a touch for the ones I manually copied as I don't know if this is from an in-memory
queue or if it Postgresql reads the contents of this regularly in order to decide what to copy.
Is that safe to do?

You can copy all of the WAL logs from your gap to the standby. If you place them in the correct location (directory designated for restore) theinstance will automatically apply them all.

Came in this morning to numerous complaints from pgpool about the standby servers being behind from the primary. Looking into it, no WAL files had been transferred since late Friday. All I did was restart the primaryand the WAL archving resumed, however, looking at the WAL files on the standby servers, this is never going to catch up. Now, I've got the archive_timeout on the primary = 600 or 10 minutes and I see WAL files in pg_xlog every 10 minutes. As they show up on the standby servers, they're also 10 minutes apart, but the primary is writing *21 and the standby's areonly up to *10. Now, like I said prior, with there being 10 minutes (600seconds) between transfers (the same pace as the WALs are generated) it will never catch up. Is this really the intended behavior? How would I get the additional WAL files over to the standbys without waiting 10 minutes to copy them one at a time?
