Hi @gustavov,
The changes to 3.0.0_update.xml
are already filed and committed here: Correct missing table alias for PostgreSQL upgrade · Issue #2989 · pkp/pkp-lib · GitHub
The second patch is to correct the issue described in this thread: Upgrade failure (Postgresql)
We’re not merging that change into the OJS distribution because we’re trying to avoid maintaining local patches of third-party code. There are some relevant issues that will solve this in another way: Test migration of ADODB to Composer dependency · Issue #2353 · pkp/pkp-lib · GitHub and https://github.com/pkp/pkp-lib/issues/2493.
Regards,
