checkWellFormedRecursion would issue "missing recursive reference" if a WITH RECURSIVE query contained a single self-reference but that self-reference was inside a top-level WITH, ORDER BY, LIMIT, etc, rather than inside the second arm of the UNION as expected. We already intended to throw more-on-point errors for such cases, but those error checks must be done before examining the UNION arm in order to have the desired results. So this patch need only move some code (and improve the comments). Per bug #18536 from Alexander Lakhin. Back-patch to all supported branches.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication (but see also below) examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level kerberos/ Tests for Kerberos/GSSAPI authentication and encryption ldap/ Tests for LDAP-based authentication locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication
