Editorial interest 78/100 Selection signal · not a rating of the site

An interactive PostgreSQL curriculum that teaches SQL fundamentals through browser-based lessons and runnable examples.

Landing page captured for the 2026-09-22 issue.
For
Experienced developers learning PostgreSQL fundamentals
Worth noticing
The curriculum pairs each lesson with a browser SQL editor and databases running in PGlite.

Field notes

The curriculum is organized into short lessons with visible exercise counts and estimated completion times, rather than a single undifferentiated SQL guide. Its examples include comparing sequential and index scans, modeling many-to-many relationships, and handling three-valued logic. The separate playground is described as loading lesson databases into PGlite so learners can edit queries outside the lesson sequence. Several later entries are marked Draft, indicating that the course is still being filled out.
