We disallow altering a column datatype within a regular table, if the table's rowtype is used as a column type elsewhere, because we lack code to go around and rewrite the other tables. This restriction should apply to partitioned tables as well, but it was not checked because ATRewriteTables and ATPrepAlterColumnType were not on the same page about who should do it for which relkinds. Per bug #17351 from Alexander Lakhin. Back-patch to all supported branches. Discussion: https://postgr.es/m/17351-6db1870f3f4f612a@postgresql.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 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
