PostgreSQL for Everything

Teams using PostgreSQL for search, queues, vectors, time series, or caching usually get a simpler stack. Recovery is where the trade-off becomes concrete.

Before adding another workload, record:

• its recovery point and recovery time targets
• whether one restore must recover every workload together
• which extensions the recovery environment needs
• the load it can add before OLTP latency becomes unacceptable
• the condition that would move it to a separate service

If those answers differ sharply across workloads, one database may have become one large failure domain.

Raphael Bauer makes the case for starting with PostgreSQL instead of adding infrastructure by default: https://www.raphaelbauer.com/posts/postgresql-everything/

If you run PostgreSQL beyond OLTP, which workload did you eventually split back out, and what forced the decision?
