Everything that has changed
- Launch
PostgreSQL 18 released
An asynchronous I/O subsystem, uuidv7() in core, skip scan for multi-column B-tree indexes, virtual generated columns, and — quietly the most useful item — planner statistics that survive pg_upgrade, removing the post-upgrade ANALYZE window during which a freshly migrated cluster plans badly.SourceLogged in the sqlite vs postgres vs mysql comparison - Launch
MariaDB 11.8 LTS ships vector search in the community server
A VECTOR column type with an approximate nearest-neighbour index reaches GA in a mainstream open-source relational engine, without an enterprise tier. It landed ahead of MySQL, whose 9.x VECTOR type still leans on HeatWave for approximate indexing, and it narrows one of pgvector's few remaining structural advantages.SourceLogged in the sqlite vs postgres vs mysql comparisonAlso affects mariadbAlso affects mysql - Funding
Databricks acquires Neon
Serverless Postgres gets absorbed into a data-platform vendor at roughly a billion dollars, on the stated thesis that agents create databases faster than humans do. Read it as confirmation that the money in this category is entirely in who operates the engine, which is why this page has no pricing column.Logged in the sqlite vs postgres vs mysql comparison
How this changelog is kept
Events are written by hand and dated to the day the change took effect, not the day we noticed. Each one names the tools it affects, so a shared change — a cloud provider raising egress prices across four products — appears on every profile it touches rather than being duplicated four times.
Everything here also flows into the site-wide changelog, which is the cross-tool feed of what is moving in developer infrastructure pricing.
