Given an updatable view with a DO ALSO INSERT ... SELECT rule, a multi-row INSERT ... VALUES query on the view fails if the VALUES list contains any DEFAULTs that are not replaced by view defaults. This manifests as an "unrecognized node type" error, or an Assert failure, in an assert-enabled build. The reason is that when RewriteQuery() attempts to replace the remaining DEFAULT items with NULLs in any product queries, using rewriteValuesRTEToNulls(), it assumes that the VALUES RTE is located at the same rangetable index in each product query. However, if the product query is an INSERT ... SELECT, then the VALUES RTE is actually in the SELECT part of that query (at the same index), rather than the top-level product query itself. Fix, by descending to the SELECT in such cases. Note that we can't simply use getInsertSelectQuery() for this, since that expects to be given a raw rule action with OLD and NEW placeholder entries, so we duplicate its logic instead. While at it, beef up the checks in getInsertSelectQuery() by checking that the jointree->fromlist node is indeed a RangeTblRef, and that the RTE it points to has rtekind == RTE_SUBQUERY. Per bug #17803, from Alexander Lakhin. Back-patch to all supported branches. Dean Rasheed, reviewed by Tom Lane. Discussion: https://postgr.es/m/17803-53c63ed4ecb4eac6%40postgresql.org |

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
