rupg-sql 0.1.84

//! The keywords of PostgreSQL, with their tokens and categories.
//!
//! @generated by `cargo xtask sql` from `vendor/postgres-19/src/include/parser/kwlist.h` and `gram.y`. Do not edit. `cargo xtask sql --check` runs in CI and fails if this file and the vendored files disagree.
//!
//! A lookup is one perfect hash probe and one comparison. The words are in the order of `kwlist.h`, which is sorted.
