Hello,
I'm hoping to get some suggestions on what to do here. I am running PostgreSQL
version 13.2 and am shipping the WAL files to a standby server. Once a day I
restart the standby server and it recovers the new WAL files that have been
shipped to it. Everything was working great until yesterday. My problem is
that the WAL recovery is now stopping before it recovers all of the available
WAL files. This happened once before and the only way I could get the WAL
recovery to go past that file was to create a fresh back and restore that. I'm
hoping to avoid that as it takes about a week to create the backup.
Here are the specifics:
* PostgreSQL version 13.2
* The primary server creates the WAL files and a scheduled process copies
them to a folder on the standby server.
* Once a day, the standby server is restared using the following command:
* "C:\Program Files\PostgreSQL\13\bin\pg_ctl" restart -D .\
* The log contains the following:

* There are many more WAL files available starting with
00000001000004190000005B but the restore process always stops at
00000001000004190000005A.
I have two questions:
* Why does the WAL file recovery process now stop after it reads
00000001000004190000005A?
* What do I need to do to get PostgreSQL to recover the rest of the
available WAL files.
Thanks in advance for any suggestions.
Sincerely,
