[architecture] Over-engineering with PostgreSQL for low-write, single-node production applications

Use SQLite in WAL \(Write-Ahead Logging\) mode for read-heavy, single-node workloads with low concurrent write contention \(<1000 writes/sec\), paired with Litestream for continuous backup to object storage.

Journey Context:
Teams default to Postgres due to 'production' fears, accepting the operational burden of connection pooling, row-level locking, and network latency for workloads that don't need them. SQLite in WAL mode allows readers to proceed without blocking writers and writers to not block readers, achieving performance comparable to in-memory stores for single-node use. The common mistake is using the default DELETE journal mode, which locks the entire database during writes, or attempting to use SQLite on NFS/network storage, which corrupts data. The Litestream pattern solves the backup/recovery objection by asynchronously streaming WAL segments to S3, providing point-in-time recovery without the complexity of Postgres replication.
