This crate provides FFI bindings to libpg_query.
By default, this library builds against a version of the C library that it has
vendored. However, if you set the LIBPG_QUERY_PATH env var when running
cargo, it will use this path to find the needed header and library
files. Specifically, it will look for $LIBPG_QUERY_PATH/include/pg_query.h
and look in $LIBPG_QUERY_PATH/lib for the compiled library.
This table shows how versions of this crate correspond to libpg_query versions:
