If you do ALTER COLUMN SET NOT NULL against an inheritance parent table, it will recurse to mark all the child columns as NOT NULL as well. This is necessary for consistency: if the column is labeled NOT NULL then reading it should never produce nulls. However, that didn't happen in the case where ALTER ... ADD PRIMARY KEY marks a target column NOT NULL that wasn't before. That was questionable from the beginning, and now Tushar Ahuja points out that it can lead to dump/restore failures in some cases. So let's make that case recurse too. Although this is meant to fix a bug, it's enough of a behavioral change that I'm pretty hesitant to back-patch, especially in view of the lack of similar field complaints. It doesn't seem to be too late to put it into v10 though. Michael Paquier, editorialized on slightly by me Discussion: https://postgr.es/m/b8794d6a-38f0-9d7c-ad4b-e85adf860fc9@enterprisedb.com |

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 examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level 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 thread/ A thread-safety-testing utility used by configure
