Understanding PostgreSQL’s Cache Hit Ratio

This article explores PostgreSQL's buffer cache hit ratio (BCHR), a metric tracked by Redgate Monitor to help you assess the health and performance of your databases. By correctly interpreting this ratio and using it with other relevant memory and IO metrics, you can identify potential bottlenecks in query execution before they impact users. Read more

Managing PostgreSQL Extensions Using Flyway

Any reliable DevOps deployment process must not only deliver the right database code but also ensure that the correct conditions exist for the deployment to succeed. For PostgreSQL databases, this includes ensuring that any extensions on which the database code relies are installed, and at the correct version. Fortunately, Flyway will automatically track which extensions are installed on a database and at what version, so we can 'propagate' these changes accurately during deployments and avoid inconsistencies in database behavior and even application breakages.

Running Flyway Pre-Migration Checks on the Database

This article demonstrates how to run a preliminary check that issues a warning, or throws an error, if the conditions aren't met for a Flyway migration to succeed. It provides some example checks for PostgreSQL databases that use Flyway SQL callbacks to ensure the server is running the correct PostgreSQL version, or that the database has a required extension installed.
