Python wrapper for libpg_query.
Inspired by psqlparse, which was authored by alculquicondor
Python protobuf types are generated from libpg_query/protobuf/pg_query.proto.
See gen_proto in Makefile for details.
Additionally, a Cython wrapper with Python bindings for certain functions
from libpg_query is provided. For example, there are wrappers for pg_query_parse_protobuf and
pg_query_deparse_protobuf, which allow converting between SQL strings and parse trees encoded as protobufs.
This snippet
demonstrates how psqlparse2 can be used to convert a SQL function into a parse tree,
and then manipulate the parse tree before converting it back into a SQL string.
pip install psqlparse2
