Обсуждение: pg_upgrade from V9.3.3 to V9.4.0

Hi all,

While we're not planning to migrate to the new version, I'm trying to gain some experience as the streaming replication
hasreally changed in this version and indicates future  
directions for it. My environment is virtualized CentO/S 6.5, and this particular server is the current primary, not a
standby.My problem is that the pg_upgrade is just hanging -  
for over an hour, before I killed it. I only see a "Verifying Cluster" message, and that's it. Even the 3 logs written
bypg_upgrade, don't really tell me any more. Am I trying to  
go too far with this upgrade? Do I need to bring it V9.3.4 first, or what? The behavior just seems a bit odd. I've only
runthis prior going from 9.2.2 to 9.3.3 and that had no issues.

I have never heard of a hang like that.  I would try V9.3.4.

Might was well go to 9.3.5 for testing.

Hi John Scalia,

I have tried pg_upgrade from 9.3.3 to 9.4.0 and i have done with the following procedure which will solve your problem.

Create .pgpass file in users home directory ~/.pgpass and add both server with their respective user & password

Now Shut down 9.3.3 & 9.4.0 cluster

Now when ever you run pg_upgrade utility the present working directory (pwd) should have write access of the current user e.g postgres

First just check if clusters are Clusters are compatible with using -c options

Example:

/opt/PostgreSQL/9.4/bin/pg_upgrade -c -v -d /tmp/PostgreSQL/9.3.3/data/ -D /tmp/PostgreSQL/9.4.0/data/ -b /opt/PostgreSQL/9.3.3/bin/ -B /opt/PostgreSQL/9.4/bin/ -p 5888 -P 5999 -U postgres

If Result says Clusters are compatible then remove -c and start upgrading

Example:

/opt/PostgreSQL/9.4/bin/pg_upgrade -v -d /tmp/PostgreSQL/9.3.3/data/ -D /tmp/PostgreSQL/9.4.0/data/ -b /opt/PostgreSQL/9.3.3/bin/ -B /opt/PostgreSQL/9.4/bin/ -p 5888 -P 5999 -U postgres

If Result says Upgrade Complete then your upgrade is completed successfully.

I am also attaching the one file for reference.

Hope this will resolve your problem.

Oh, so you are thinking it is waiting for a password?  Wouldn't it say
"Password:"?

I saw nothing on the terminal, nor anything in the logfiles indicating a password request.
