I’m also just starting out and testing out the temporal-sql-tool to see how it works and I experience the same thing on PostgreSQL version 16.1 updating from v1.9 to any higher version following the README in the Github repository temporal/tools/sql/README.md at main · temporalio/temporal .
I would be really curious if this schema update doesn’t work, what are the alternatives if there are updates to the schema that I want to deploy?
