It's important to know which version of Postgres you are running as each major version has different features and may cause breaking changes. You may also need to update your schema when upgrading or downgrading to a major Postgres version.
Run the following query using the SQL Editor in the Zuvo Studio:
select
version();
Which should return something like:
PostgreSQL 15.1 on aarch64-unknown-linux-gnu, compiled by gcc (Ubuntu 10.3.0-1ubuntu1~20.04) 10.3.0, 64-bit
This query can also be executed via psql or any other query editor if you prefer to connect directly to the database.
