The right mix of DDL and VACUUM could corrupt a catalog page header such that PageIsVerified() durably fails, requiring a restore from backup. This affects only catalogs that both have a syscache and have DDL code that uses syscache tuples to construct updates. One of the test permutations shows a variant not yet fixed. This makes !TransactionIdIsValid(TM_FailureData.xmax) possible with TM_Deleted. I think core and PGXN are indifferent to that. Per bug #17821 from Alexander Lakhin. Back-patch to v13 (all supported versions). The test case is v17+, since it uses INJECTION_POINT. Discussion: https://postgr.es/m/17821-dd8c334263399284@postgresql.org |

Test extensions and libraries ============================= src/test/modules contains PostgreSQL extensions that are primarily or entirely intended for testing PostgreSQL and/or to serve as example code. The extensions here aren't intended to be installed in a production server and aren't suitable for "real work". Furthermore, while you can do "make install" and "make installcheck" in this directory or its children, it is NOT ADVISABLE to do so with a server containing valuable data. Some of these tests may have undesirable side-effects on roles or other global objects within the tested server. "make installcheck-world" at the top level does not recurse into this directory. Most extensions have their own pg_regress tests or isolationtester specs. Some are also used by tests elsewhere in the tree. If you're adding new hooks or other functionality exposed as C-level API this is where to add the tests for it.
