答复: [External] Re: pgadmin--pgagent---the process hang by unknow reasons

Hi Dave

Thanks for your update. I collect logs for your reference.
By the way. Is there any upgrade document which mentioned this scenario ? upgrade pgagent_10 3.4 to pgagent_10 4.0.
5: start pgagent process with new version pgagent.
With what error? Anything in the pgAgent log or /var/log/messages etc?
There is no errors.The pgagent process disappear after execute the command.
On pgagent_10 3.4 version. There is a pgagent_10 process running.

The pgagent_10 4.0 trace log also no errors. Look like it terminate unexpected.

Hi Dave

The command output is :

My test system. All commands executed on this system.
Before upgrade pgagent. I execute follow in steps.

1: backup and restore production database.
2: install pgagent by yum command .
Yum install pgagent_10
Yum downgrade pgagent_10. (Then pgagent backup to 3.4 )

3: start pgagent process. Make sure pgagent running on normal state.

4: execute yum upgrade command to pgagent 4.0

5: start pgagent process with new version pgagent.
Failed.

With what error? Anything in the pgAgent log or /var/log/messages etc?

6: try to upgrade by the upgrade script.

That indicates that pgAgent 4.0 is installed, not 4.2. I would suggest not trying to build it yourself at this stage.

Our production system.

Right - that looks like 3.4 is installed, as expected.

Hi

It sounds like the extension hasn't been installed properly at the operating system level - what is the output from:

ls -al /usr/pgsql-10/share/extension

Thanks for your quick response.

I try this command on 4.0 and 4.2. I got a warning that the extension not exist.

Would you like to help me narrow down this upgrade issue ？ Thanks

upgrade path

yum install pgagent_10
\i pgagent--3.4--4.0.sql

3.4 – 4.0

compile and build. (install cmake and Boost)

\i pgagent--3.4--4.2.sql
create extension pgagent;

Currently pgagent_10 3.4.0 env installed by my teammate. He told me that he install it by yum command and execute a script.
Then those pgagent tables created by this script. There is no extension exist. But those pgagent table exist.

I think the message is wrong (which I'll fix if you can confirm) - it should be:
