A Working Python VM Written Entirely in PL/PgSQL

This repo literally turns CPython internals into rows and stored procedures: object rows, regproc type slots, and an interpreter loop (py_eval_frame) that dispatches opcode handler functions in SQL. It's a clever, hands-on exploration — 103 SQL files, a REPL and 87 tests show serious follow-through — but it's primarily an impressive engineering demo rather than a practical production runtime.
