Add labels to PostgreSQL records with Jev

pg_typesafe lets PostgreSQL send selected text to Jev for a category, rating, or yes-or-no estimate. Its guide covers the connection and the limits of asking an outside service.

Our summary

PostgreSQL is a system for keeping organized records. This add-on lets a database request ask Jev about a record's meaning, rather than only matching exact words or numbers. The program names the allowed answers before sending the selected text.

The guide shows installation, private-key setup, and questions written inside database requests. Jev returns one category, an estimated likelihood of yes, or a rating along described levels. Those answers can help a program label stored records or choose which to examine first.

Checking a large collection may contact Jev many times. The extra calls can delay work, increase the bill, and expose information unnecessarily. Start with representative records, restrict simultaneous requests, and choose a clear response when the service fails or gives an uncertain answer.

Key takeaways

Select only the fields needed for the judgment.
Ask for a known kind of answer, not a written paragraph.
Count likely calls and plan for service failures before checking a large collection.
