The following snippet demonstrates how to get a query fingerprint, return a normalized query, parse SQL, and parse a PL/PgSQL function.

import pprint

import pgparse

sql = "SELECT * FROM pg_catalog.pg_class WHERE relname = 'foo'"
print('Fingerprint: {}'.format(pgparse.fingerprint(sql)))
print('Normalized: {!r}'.format(pgparse.normalize(sql)))
parsed = pgparse.parse(sql)
pprint.pprint(parsed)

func = """\
CREATE FUNCTION sales_tax(subtotal real) RETURNS real AS $$
        BEGIN
            RETURN subtotal * 0.06;
        END;
        $$ LANGUAGE plpgsql;
"""
parsed = pgparse.parse_pgsql(func)
pprint.pprint(parsed)
