pgColumnar 1.0-alpha4 release notes
Release date: 2026-09-17 Previous release: 1.0-alpha3 (2026-09-02)
pgColumnar is a columnar table access method for PostgreSQL. This is the fourth alpha. Its theme is layout and skipping. A table can now be laid out on the Hilbert curve, which keeps neighbouring keys closer together than Z-order does. A star-schema join now skips fact-table groups and rejects non-matching rows, and it does …
Version 19: 71 commits on REL_19_STABLE. Version 20: 46 commits on master. Reverted out of 19: 74 commits, in 6 reverts. Six features tracked, 2 still shipping. Window closed at d8408e8d682.
71 commits landed on the 19 branch in nine days. The six reverts in the same window name 74 commits between them.
Six reverts, newest first.
Benchmarking huge_pages on a 128 GB PostgreSQL 18 system shows throughput gains are modest — but page table overhead at 4KB pages can consume up to 20% of total RAM. Use PSI to find where your system is actually stalling before making the call. Part 2 of 3.

Previous release: 1.0-alpha (2026-08-04)
pgColumnar is a columnar table access method for PostgreSQL. This is the second alpha. It adds read-only Apache Iceberg support, reads and writes over S3-compatible object storage, a maintenance daemon, and a broad round of statistics, planner, performance, and security work. The on-disk native format (PGCN v1) is unchanged; existing tables are read and written as before.
This release requires one …
A pile of containers is not a shipment. A shipment is containers plus a manifest.
Apache Iceberg is the manifest. It is not a file format, it is a table format: a metadata layer that records exactly which Parquet files make up a table at every point in time. That one idea buys you things we used to think required a warehouse. Transactions on object storage, so writers never corrupt …
Tuning shared_buffers isn't just about peak throughput — it's about how much CPU and disk I/O a system consumes per unit of work. The 25% default can require up to 5x more disk I/O than very low or very high allocation. Part 1 of 3.
Engineering leaders work hard to protect their teams from burnout — improving processes, hiring strong talent, and adjusting on-call rotations. But if your team still looks exhausted, the real issue may not be the rotation at all. It’s often the underlying database and infrastructure quietly triggering the same incidents over and over.
Released in July 2025, NIST SP 800-63 Revision 4 introduced new requirements for authentication strength, identity proofing, and federation security. Many organizations still haven't assessed their systems against these updated standards. Learn what changed, why it matters for compliance, and how to evaluate your current identity controls against the new framework.
