===================================================================
 :mod:`pglast.ast` --- Python classes representing PG parser nodes
===================================================================

The module implements a set of *data* classes, one for each ``C`` structure defined in several
PostgreSQL headers, primarily those in the `include/nodes/`__ directory.

__ https://github.com/pganalyze/libpg_query/blob/27b2af9/src/postgres/include/nodes

The :class:`pglast.ast.Node` is an abstract class that implements the common behaviour of all
the concrete classes. In particular any node can be :meth:`compared <pglast.ast.Node.__eq__>`
with another instance, is able to :meth:`serialize <pglast.ast.Node.__call__>` itself and can
be :meth:`altered <pglast.ast.Node.__setattr__>`.
