PGXN

Isok^[1] is a PostgreSQL extension for monitoring and validating data using SQL queries.

Queries find problems. Isok builds on this and tracks changes in problematic data, changes that might or might not indicate a new problem. When configured to accept some questionable rows but not others of the same kind, Isok acts like a “soft trigger”, with scheduling and note-taking features to support the management of problem resolution.

Useful for "zero code required" batch-based data validation. Most useful when review is required to determine whether a questionable data pattern should be allowed to remain in a database.
