postgresql-storage-check

To check PostgreSQL storage health, run SQL queries and kubectl commands to assess PVC capacity, in-pod disk usage, and database object sizes across multiple Patroni pods to prevent outages and performance degradation.

Your PostgreSQL PVC may be filling up due to WAL accumulation, inactive replication slots, or table bloat. Diagnose these specific storage consumers by running operational checks with SQL queries and kubectl commands across your Patroni pods.

Yes, this storage check explicitly supports Kubernetes deployments using Patroni and pgskipper-operator. It handles environment-aware credentials and performs inline data directory discovery across multiple pods within these specific cluster architectures.

To find the largest database objects causing PostgreSQL disk pressure, run a storage-check workflow that surfaces PVC usage, per-pod disk usage, and top database objects by size, prioritizing maintenance actions to resolve the pressure.

Yes, you can estimate table bloat and analyze WAL replication slots in PostgreSQL through targeted SQL queries. This diagnostic capability allows you to plan maintenance and identify inactive slots causing storage accumulation.

The best way to diagnose WAL accumulation across multiple PostgreSQL pods is executing end-to-end operational checks using SQL queries and kubectl commands, which provides inline data directory discovery and environment-aware credential handling.
