Move test modules from contrib to src/test/modules This is advance preparation for introducing even more test modules; the easy solution is to add them to contrib, but that's bloated enough that it seems a good time to think of something different. Moved modules are dummy_seclabel, test_shm_mq, test_parser and worker_spi. (test_decoding was also a candidate, but there was too much opposition to moving that one. We can always reconsider later.)

Re-add BRIN isolation test This time, instead of using a core isolation test, put it on its own test module; this way it can require the pageinspect module to be present before running. The module's Makefile is loosely modeled after test_decoding's, so that it's easy to add further tests for either pg_regress or isolationtester later. Backpatch to 9.5.

Keep track of transaction commit timestamps Transactions can now set their commit timestamp directly as they commit, or an external transaction commit timestamp can be fed from an outside system using the new function TransactionTreeSetCommitTsData(). This data is crash-safe, and truncated at Xid freeze point, same as pg_clog. This module is disabled by default because it causes a performance hit, but can be enabled in postgresql.conf requiring only a server restart. A new test in src/test/modules is included. Catalog version bumped due to the new subdirectory within PGDATA and a couple of new SQL functions.

dummy_seclabel \
Add the "snapshot too old" feature This feature is controlled by a new old_snapshot_threshold GUC. A value of -1 disables the feature, and that is the default. The value of 0 is just intended for testing. Above that it is the number of minutes a snapshot can reach before pruning and vacuum are allowed to remove dead tuples which the snapshot would otherwise protect. The xmin associated with a transaction ID does still protect dead tuples. A connection which is using an "old" snapshot does not get an error unless it accesses a page modified recently enough that it might not be able to produce accurate results. This is similar to the Oracle feature, and we use the same SQLSTATE and error message for compatibility.

Add Bloom filter implementation. A Bloom filter is a space-efficient, probabilistic data structure that can be used to test set membership. Callers will sometimes incur false positives, but never false negatives. The rate of false positives is a function of the total number of elements and the amount of memory available for the Bloom filter. Two classic applications of Bloom filters are cache filtering, and data synchronization testing. Any user of Bloom filters must accept the possibility of false positives as a cost worth paying for the benefit in space efficiency. This commit adds a test harness extension module, test_bloomfilter. It can be used to get a sense of how the Bloom filter implementation performs under varying conditions. This is infrastructure for the upcoming "heapallindexed" amcheck patch, which verifies the consistency of a heap relation against one of its indexes.

Allow on-the-fly capture of DDL event details This feature lets user code inspect and take action on DDL events. Whenever a ddl_command_end event trigger is installed, DDL actions executed are saved to a list which can be inspected during execution of a function attached to ddl_command_end. The set-returning function pg_event_trigger_ddl_commands can be used to list actions so captured; it returns data about the type of command executed, as well as the affected object. This is sufficient for many uses of this feature. For the cases where it is not, we also provide a "command" column of a new pseudo-type pg_ddl_command, which is a pointer to a C structure that can be accessed by C code. The struct contains all the info necessary to completely inspect and even reconstruct the executed command. There is no actual deparse code here; that's expected to come later. What we have is enough infrastructure that the deparsing can be done in an external extension. The intention is that we will add some deparsing code in a later release, as an in-core extension. A new test module is included. It's probably insufficient as is, but it should be sufficient as a starting point for a more complete and future-proof approach.

Add CASCADE support for CREATE EXTENSION. Without CASCADE, if an extension has an unfullfilled dependency on another extension, CREATE EXTENSION ERRORs out with "required extension ... is not installed". That is annoying, especially when that dependency is an implementation detail of the extension, rather than something the extension's user can make sense of. In addition to CASCADE this also includes a small set of regression tests around CREATE EXTENSION.

test_parser \
Add TAP tests for pg_dump This TAP test suite will create a new cluster, populate it based on the 'create_sql' values in the '%tests' hash, run all of the runs defined in the '%pgdump_runs' hash, and then for each test in the '%tests' hash, compare each run's output the the regular expression defined for the test under the 'like' and 'unlike' functions, as appropriate. While this test suite covers a fair bit of ground (67% of pg_dump.c and quite a bit of the other files in src/bin/pg_dump), there is still quite a bit which remains to be added to provide better code coverage. Still, this is quite a bit better than we had, and has found a few bugs already (note that the CREATE TRANSFORM test is commented out, as it is currently failing). Idea for using the TAP system from Tom, though all of the code is mine.

test_pg_dump \
Add test scaffolding for exercising optimizer's predicate-proof logic. The predicate-proof code in predtest.c is a bit hard to test as-is: you have to construct a query whose plan changes depending on the success of a test, and in tests that have been around for awhile, it's always possible that the plan shape is now being determined by some other factor. Our existing regression tests aren't doing real well at providing full code coverage of predtest.c, either. So, let's add a small test module that allows directly inspecting the results of predicate_implied_by() and predicate_refuted_by() for arbitrary boolean expressions. I chose the set of tests committed here in order to get reasonably complete code coverage of predtest.c just from running this test module, and to cover some cases called out as being interesting in the existing comments. We might want to add more later. But this set already shows a few cases where perhaps things could be improved. Indeed, this exercise proves that predicate_refuted_by() is buggy for the case of clause_is_check = true, though fortunately we aren't using that case anywhere yet. I'll look into doing something about that in a separate commit. For now, just memorialize the current behavior. Discussion: https://postgr.es/m/5983.1520487191@sss.pgh.pa.us

RLS fixes, new hooks, and new test module In prepend_row_security_policies(), defaultDeny was always true, so if there were any hook policies, the RLS policies on the table would just get discarded. Fixed to start off with defaultDeny as false and then properly set later if we detect that only the default deny policy exists for the internal policies. The infinite recursion detection in fireRIRrules() didn't properly manage the activeRIRs list in the case of WCOs, so it would incorrectly report infinite recusion if the same relation with RLS appeared more than once in the rtable, for example "UPDATE t ... FROM t ...". Further, the RLS expansion code in fireRIRrules() was handling RLS in the main loop through the rtable, which lead to RTEs being visited twice if they contained sublink subqueries, which prepend_row_security_policies() attempted to handle by exiting early if the RTE already had securityQuals. That doesn't work, however, since if the query involved a security barrier view on top of a table with RLS, the RTE would already have securityQuals (from the view) by the time fireRIRrules() was invoked, and so the table's RLS policies would be ignored. This is fixed in fireRIRrules() by handling RLS in a separate loop at the end, after dealing with any other sublink subqueries, thus ensuring that each RTE is only visited once for RLS expansion. The inheritance planner code didn't correctly handle non-target relations with RLS, which would get turned into subqueries during planning. Thus an update of the form "UPDATE t1 ... FROM t2 ..." where t1 has inheritance and t2 has RLS quals would fail. Fix by making sure to copy in and update the securityQuals when they exist for non-target relations. process_policies() was adding WCOs to non-target relations, which is unnecessary, and could lead to a lot of wasted time in the rewriter and the planner. Fix by only adding WCO policies when working on the result relation. Also in process_policies, we should be copying the USING policies to the WITH CHECK policies on a per-policy basis, fix by moving the copying up into the per-policy loop. Lastly, as noted by Dean, we were simply adding policies returned by the hook provided to the list of quals being AND'd, meaning that they would actually restrict records returned and there was no option to have internal policies and hook-based policies work together permissively (as all internal policies currently work). Instead, explicitly add support for both permissive and restrictive policies by having a hook for each and combining the results appropriately. To ensure this is all done correctly, add a new test module (test_rls_hooks) to test the various combinations of internal, permissive, and restrictive hook policies. Largely from Dean Rasheed (thanks!): CAEZATCVmFUfUOwwhnBTcgi6AquyjQ0-1fyKd0T3xBWJvn+xsFA@mail.gmail.com Author: Dean Rasheed, though I added the new hooks and test module.
