Errors from archive restore from S3 and wrong size archive file

От

I have been troubleshooting this for the past few days with little headway.

I have a test environment where my archive directory is an S3 bucket

I use rclone to transfer the files

My recovery.conf file looks like this

restore_command = '/var/lib/postgresql/walsfroms3.sh %f %p'

recovery_target_time = '2018-08-02 16:05:04.859461+00'


which is a call to

this script

export S3_DEST="bla/bla/bla/wal_files"


rclone -v --log-file=/var/lib/postgresql/rclone.log copy remote:${S3_DEST}/$1 $2 

On the attempt to restore. I keep getting the following error

2018-08-02 17:14:42.157 UTC [] [193825]: [2-1] user=,db=,host= LOG:  starting point-in-time recovery to 2018-08-02 16:05:04.859461+00

2018-08-02 17:14:49.330 UTC [] [193825]: [3-1] user=,db=,host= FATAL:  archive file "000000010000000000000002" has wrong size: 38 instead of 16777216

HOWEVER

My rclone logfile and RECOVERYXLOG has the correct file in there.

~ $ cat rclone.log

2018/08/02 17:14:42 NOTICE: Config file "/var/lib/postgresql/.config/rclone/rclone.conf" not found - using defaults

It's almost as if the recovery is reading the S3 folder name instead of the file name. Any help would be appreciated.

I don’t think RECOVERYXLOG should be a directory; that should be the WAL file being restored.  Postgres is trying to restore the directory instead of the file thus the error.
