I am working on upgrading from V11 to V12 on Debian. My first attempt failed, and I have figured out that this is because I have added extensions to the V11 DB, at least one of which was not installed using the Debian packages. So, it looks like i need to install these before doing the upgrade, correct? This brings up a chicken or egg issue however. We are creating the extensions, like this: CREATE EXTENSION emailaddr with schema ica So, to accomplish this, I would need to create the ice schema, and the user it "belongs" to before I run pg_upgradecluster. This raises 2 questions
There are two parts to adding extensions. First you install the *files* the extension needs. If you build from source this happens when you say `make install`. Or if you use pgxn, when you say `pgxn install foo`. On Ubuntu this will add the *.sql and *.control files to /usr/share/postgresql/12/extension, and the *.so files to /usr/lib/postgresql/12/lib (so I assume Debian is similar). You can do that before running pg_upgradecluster.
The second part is saying CREATE EXTENSION, which adds the extension to the current database. pg_upgradecluster should handle that for you; it shouldn't require any extra steps.
I hope this helps! Yours, -- Paul ~{:-) pj@xxxxxxxxxxxxxxxxxxxxxxxx
