Re: wrong size archive file

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<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?
