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.
Both reverts landed after Robert Haas asked the pgsql-hackers list on August 25 whether any of six heavily patched features should come out before 19 ships. One of the two was on his list. One was not.

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 …
Examine your own work honestly. Which job are you doing? If everything you contributed last quarter could be described as construction, start climbing. Learn the bearing loads. Learn the customer.

He was very tall in a way that seemed apologetic, as if he had been issued the height by mistake and was still trying to give it back. He had a laugh he did not perform. When the moderator asked a genuinely stupid question, Dorian Vale did not smirk at the audience the way the other panelists did. He answered it seriously, and well, and the questioner sat down looking …
