In plain words
SQL-tap is a transparent proxy that captures and displays SQL queries in real-time for PostgreSQL and MySQL databases. It works by parsing the database wire protocol and showing queries in a terminal interface, allowing users to run EXPLAIN on any captured query. The tool requires no changes to application code—users simply redirect their database connection to a different port to start monitoring traffic.
