Thread: pgsql: pg_upgrade: run all data type checks per connection
pg_upgrade: run all data type checks per connection The checks for data type usage were each connecting to all databases in the cluster and running their query. On clusters which have a lot of databases this can become unnecessarily expensive. This moves the checks to run in a single connection instead to minimize setup and teardown overhead.
