The real PostgreSQL parser, exposed for nodejs.
Primarily used for the node.js parser and deparser pgsql-parser
npm install libpg-queryconst parser = require('libpg-query');
parser.parseQuery('select 1').then(console.log);Parses the sql and returns a Promise for the parse tree (or returns the parse tree directly in the sync version). May reject with/throw a parse error.
The return value is an array, as multiple queries may be provided in a single string (semicolon-delimited, as Postgres expects).
Parses the contents of a PL/PGSql function, from a CREATE FUNCTION declaration, and returns a Promise for the parse tree (or returns the parse tree directly in the sync version). May reject with/throw a parse error.

This is based on the output of libpg_query. This wraps the static library output and links it into a node module for use in js.
