+PL/PRQL is a PostgreSQL extension that lets you write functions with PRQL.
 
 PL/PRQL functions serve as intermediaries, compiling the user's PRQL code into SQL statements that PostgreSQL executes. The extension is based on the [pgrx](https://github.com/pgcentralfoundation/pgrx) for developing PostgreSQL extensions in Rust. This framework manages the interaction with PostgreSQL's internal APIs, type conversions, and other function hooks necessary to integrate PRQL with PostgreSQL.
