Re: Proper way to restore from a basebackup without the WAL-files?

[Gustav Karlsson <gustav.karlsson@xxxxxxx>]

Ok, thanks. That was actually what I ended up doing, but I get some warnings in the log. For example:

< 2015-12-15 00:00:58.206 CET ><  ><  >ERROR:  failed to re-find parent key in index “myindex_idx" for deletion target page 101400

..

Is that to be expected? 

Also, will the server be in a state where I can start replication to a slave? (given a fresh backup from the new timeline)

Regards,

Gustav

If you absolutely must use the pg_basebackup as your source and I'm assuming you have a tarball without any of WAL files, you could expand the tarball into you data directory, and use pg_resetxlog to "fool" the master into starting up. I only say "fool" as it just builds you a blank WAL file which this system can use as its integrity check and properly start.

Hi,

What is the proper way start a new master from a basebackup when you do not have the WAL-files?

We are using postgresql 9.4.
