Ask Jev questions about records in PostgreSQL

pg-jev connects PostgreSQL, a system for storing organized records, to Jev. It lets a database ask questions about selected information and use the answers in later searches.

Our summary

PostgreSQL stores information in tables of records. This experimental add-on lets it send selected information to Jev and ask a question. The answer can be a likelihood of yes, a choice from a list, or a rating on described levels.

The guide explains how to add the connection and supply a private service key. A database request can then include a Jev question. The answer becomes another value the database can display, save, sort, or use to narrow a later search.

Unlike an ordinary database calculation, each judgment contacts an outside service. That adds waiting time and cost, and selected records leave the database. Protect private information, limit the number of calls, and decide how to handle uncertain or missing answers.

Key takeaways

  1. Send only the information the question needs.
  2. The database can use Jev's answer like another stored value.
  3. An easy connection does not make the judgment exact or private.

The repository documents an experimental extension. JevMade did not install it, send database data, or repeat its examples.
