pg-query-native

The real PostgreSQL parser for nodejs.

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.

All credit for the hard problems goes to Lukas Fittl.

How to re-buid

git clone -b 10-latest git://github.com/lfittl/libpg_query
cd libpg_query
make

Then get the .a file and drop it in the folder in this repo.

Installation

npm install pg-query-native-latest
