Convert SQL between
MySQL, Postgres & SQLite

What this handles

• Auto-increment primary keys — AUTO_INCREMENT (MySQL) ⇄ SERIAL (Postgres) ⇄ INTEGER PRIMARY KEY AUTOINCREMENT (SQLite)
• Identifier quoting — backticks (MySQL) ⇄ double quotes (Postgres/SQLite)
• String concatenation — CONCAT(a, b) (MySQL) ⇄ a || b (Postgres/SQLite)
• NOW() → CURRENT_TIMESTAMP when converting away from MySQL

What it doesn't handle

This is pattern matching, not a real SQL parser — it won't catch every dialect-specific function, window function syntax, or data type nuance (MySQL's TINYINT(1) booleans, Postgres arrays, SQLite's dynamic typing, and so on). Always review the output before running it against a real database.
