Re: pgagent_upgrade.sql does not exist

Hi PgAdmin Team,

I'm not sure if this is the right channel, but there's mention of pgagent in the PgAdmin docs [1].  I have been trying to fix a customer's pgagent install, and this is the following information printed when starting up pgagent:

```

-bash-4.2$ /usr/edb/as13/bin/pgagent -l2 -f host=127.0.0.1 user=enterprisedb dbname=postgres
Thu Sep 9 20:15:10 2021 DEBUG: Creating primary connection

Thu Sep 9 20:15:10 2021 DEBUG: dbname: postgres
Thu Sep 9 20:15:10 2021 DEBUG: host: 127.0.0.1

Thu Sep 9 20:15:10 2021 DEBUG: Database sanity check
Thu Sep 9 20:15:10 2021 ERROR: Unsupported schema version: 3. Version 4 is required - please run pgagent_upgrade.sql.
-bash-4.2$ find /usr/edb/ -name "pgagent_upgrade.sql"
-bash-4.2$

```

Notice that I could not find pgagent_upgrade.sql anywhere.  I also looked in the PgAdmin repository, but could not find it:

```

$ find . -name "pgagent_upgrade.sql"
$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

```

I also looked at the pgagent repository (git@github.com:postgres/pgagent.git), and could not find the file.  Perhaps this log message is an artifact that needs to be removed?

FWIW, I managed to fix the customer's pgagent install by executing `ALTER EXTENSION "pgagent" UPDATE;`, as specified by pg_upgrade.

Please let me know if you need more info here.

Regards,
