PostgreSQL 18 introduces the extension_control_path GUC, allowing extensions to be installed in arbitrary directories rather than the system-wide extension directory. This change decouples extension location from the core installation structure, enabling more flexible deployment strategies. The update removes the previous hard constraint that forced all extensions into a fixed system path.
Extensions can now reside in custom directories via extension_control_path
Ends the requirement to install extensions into the system directory
Shaun Thomas highlights a significant but overlooked feature in Postgres 19: enhanced control over manual CHECKPOINT operations. Previously, issuing a manual checkpoint was a blunt instrument that triggered an immediate, uncontrolled flush of pending writes to disk. The new release introduces finer-grained mechanisms to manage this process, addressing storage I/O spikes that can occur when background checkpoints or manual invocations overwhelm the system.
Manual CHECKPOINT behavior is enhanced in Postgres 19 for better I/O management.
DBAs can now invoke checkpoints with more predictable resource impact.
Review Postgres 19 release notes for specific syntax changes to checkpoint control.
Tuning storage performance should account for these new checkpoint options.
Fleet impact: For fleets running heavy write workloads, Postgres 19's improved manual checkpoint control allows DBAs to flush data without causing sudden I/O storms that could impact latency. Ensure your operational scripts for maintenance windows are updated to leverage these new parameters if available, and monitor storage throughput during manual checkpoints to validate the reduced impact.
