I don't think you need to move anything out of pg_xlog to WAL archive Directory. You should remove all files from pg_xlogs directory on recovery database server too (i.e  Run rm pg_xlog/* ) 

Please remove the 00000001000000000000004C from WAL archive directory, remove all files from pg_xlogs on recovery database  and try to startup database ?

Quick summary of what I did and the archive file:

I shut down postgres via pg_ctl stop

I renamed the existing data directory

I created a new directory for the restore with the old name

Unzipped and untarred the base.tar.gz file

 

In the pg_xlog, of the renamed data directory, there is the following:

postgres@xpostgw2d:/postgresql/data/GRIZZ??/pg_xlog>ls -ltr

total 16432

-rw------- 1 postgres vfabric      305 Oct  9 14:56 00000001000000000000002B.000

drwx------ 2 postgres vfabric     4096 Oct 21 14:30 archive_status

 

I copied the 00000001000000000000004C.00000020.backup file to 00000001000000000000004C in the archive directory /postgresql/archive/GRIZZ.

 

The recovery.conf file has the following param:

 

restore_command = 'cp /postgresql/archive/GRIZZ/%f "%p"'

Thanks. Backup looks good. 

 

How's your recovery.conf look like? Can you provide 'ls -l' on archive file "00000001000000000000004C" from your WAL directory?

I have created a script to run the pg_basebackup utility.  The options it uses are:

pg_basebackup -D $BACKUP_DIR/$TIMEINFO -F t -z -Z 9 –x

where $BACKUP_DIR is set to our backup directory and $TIMEINFO is set to TIMEINFO=`date +%Y%m%d_%H%M%S`.

 

The backup looks ok when I unzip it and untar it.  As it is being created, it switches to the next WAL file and the first one is way small.

Before going into recovery discussion, I would like to learn about how did you take a backup ?  Have you followed "Making A Base Backup" procedure documented in http://www.postgresql.org/docs/9.2/static/continuous-archiving.html ?

Good afternoon,

I am testing out recovery on 9.2 postgres and I am getting the following message when I try to start up the cluster:



FATAL:  archive file "00000001000000000000004C" has wrong size: 305 instead of 16777216



This archive log was active at the start of the backup and is not 16M in size in the original pg_xlog.  How do I get around this?  Is there a fix for this?
