Dears,
We need help with upgrading PostgreSql v15 to v16 on z/Linux Red Hat
Enterprise Linux 8 for IBM zSystems -AppStream.
We have tried 3 methods so far, all fail.
Server connection to external pages is prohibited, we cannot download
the packaged directly from the web link
We were able to disable module 15 and enable module 16, it replaced only
v15 binaries, so we could not proceed with upgrade using pg_upgrade --
link, because v15 were gone.....
Backup/ restore failed also with missing database, users, etc.
When we tried module switch (disable v15, enable v16), yum install
postgresql-update/ postgresl-setup --upgrade, all went fine (i.e
upgrading database OK), service 16 started,
Binaries were installed under different path, but database and users
were missing. We have recreated the database, restore failed, users
denied, and so on.....
This needs some clarification:
1) When you say module do you mean package?
2) If 'Server connection to external pages is prohibited ..." how did
you get the RPM packages?
3) What do you mean by 'disable module 15'?
4)'restore failed' restoring what?
5) What where the error messages from the failed restore?
yum.repos.d]# yum module list | grep postgres
*postgresql 15 [e] client, server
[d] PostgreSQL server and client module *
*postgresql 16 client, server
[d] PostgreSQL server and client module*
rpm -qa | grep "postgresql"
*postgresql-private-libs-16.8-1.module+el8.10.0+22867+e4e13b1c.s390x*
*postgresql-private-devel-16.8-1.module+el8.10.0+22867+e4e13b1c.s390x*
*postgresql-16.8-1.module+el8.10.0+22867+e4e13b1c.s390x*
*postgresql-server-16.8-1.module+el8.10.0+22867+e4e13b1c.s390x*
Could you advise us, what might be wrong, which package is suitable and
steps to do the upgrade, please? Is it something wrong with packages we
have, or module misconfiguration, or....
