Tom Lane ea5ae4cae6 Fix inability to reference CYCLE column from inside its CTE. 
Such references failed with "cache lookup failed for type 0"
because we didn't resolve the type of the CYCLE column until after
analyzing the CTE's query.  We can just move that processing
to before the recursive parse_sub_analyze call, though.

While here, invent a couple of local variables to make this
code less egregiously wider-than-80-columns.

Per bug #17723 from Vik Fearing.  Back-patch to v14 where
the CYCLE feature was added.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	https://www.postgresql.org/download/

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
