Andres Freund	578b229718	Remove WITH OIDS support, change oid catalog column visibility. ... Previously tables declared WITH OIDS, including a significant fraction of the catalog tables, stored the oid column not as a normal column, but as part of the tuple header. This special column was not shown by default, which was somewhat odd, as it's often (consider e.g. pg_class.oid) one of the more important parts of a row. Neither pg_dump nor COPY included the contents of the oid column by default. The fact that the oid column was not an ordinary column necessitated a significant amount of special case code to support oid columns. That already was painful for the existing, but upcoming work aiming to make table storage pluggable, would have required expanding and duplicating that "specialness" significantly. WITH OIDS has been deprecated since 2005 (commit ff02d0a05280e0). Remove it. Removing includes: - CREATE TABLE and ALTER TABLE syntax for declaring the table to be WITH OIDS has been removed (WITH (oids[ = true]) will error out) - pg_dump does not support dumping tables declared WITH OIDS and will issue a warning when dumping one (and ignore the oid column). - restoring an pg_dump archive with pg_restore will warn when restoring a table with oid contents (and ignore the oid column) - COPY will refuse to load binary dump that includes oids. - pg_upgrade will error out when encountering tables declared WITH OIDS, they have to be altered to remove the oid column first. - Functionality to access the oid of the last inserted row (like plpgsql's RESULT_OID, spi's SPI_lastoid, ...) has been removed. The syntax for declaring a table WITHOUT OIDS (or WITH (oids = false) for CREATE TABLE) is still supported. While that requires a bit of support code, it seems unnecessary to break applications / dumps that do not use oids, and are explicit about not using them. The biggest user of WITH OID columns was postgres' catalog. This commit changes all 'magic' oid columns to be columns that are normally declared and stored. To reduce unnecessary query breakage all the newly added columns are still named 'oid', even if a table's column naming scheme would indicate 'reloid' or such. This obviously requires adapting a lot code, mostly replacing oid access via HeapTupleGetOid() with access to the underlying Form_pg_*->oid column. The bootstrap process now assigns oids for all oid columns in genbki.pl that do not have an explicit value (starting at the largest oid previously used), only oids assigned later by oids will be above FirstBootstrapObjectId. As the oid column now is a normal column the special bootstrap syntax for oids has been removed. Oids are not automatically assigned during insertion anymore, all backend code explicitly assigns oids with GetNewOidWithIndex(). For the rare case that insertions into the catalog via SQL are called for the new pg_nextoid() function can be used (which only works on catalog tables). The fact that oid columns on system tables are now normal columns means that they will be included in the set of columns expanded by * (i.e. SELECT * FROM pg_class will now include the table's oid, previously it did not). It'd not technically be hard to hide oid column by default, but that'd mean confusing behavior would either have to be carried forward forever, or it'd cause breakage down the line. While it's not unlikely that further adjustments are needed, the scope/invasiveness of the patch makes it worthwhile to get merge this now. It's painful to maintain externally, too complicated to commit after the code code freeze, and a dependency of a number of other patches. Catversion bump, for obvious reasons.

Joe Conway	25542d77dd	Add partitioned table support to sepgsql ... The new partitioned table capability added a new relkind, namely RELKIND_PARTITIONED_TABLE. Update sepgsql to treat this new relkind exactly the same way it does RELKIND_RELATION. In addition, add regression test coverage for partitioned tables. Issue raised by Stephen Frost and initial patch by Mike Palmiotto. Review by Tom Lane and Robert Haas, and editorializing by me.

Tom Lane	18555b1323	Establish conventions about global object names used in regression tests. ... To ensure that "make installcheck" can be used safely against an existing installation, we need to be careful about what global object names (database, role, and tablespace names) we use; otherwise we might accidentally clobber important objects. There's been a weak consensus that test databases should have names including "regression", and that test role names should start with "regress_", but we didn't have any particular rule about tablespace names; and neither of the other rules was followed with any consistency either. This commit moves us a long way towards having a hard-and-fast rule that regression test databases must have names including "regression", and that test role and tablespace names must start with "regress_". It's not completely there because I did not touch some test cases in rolenames.sql that test creation of special role names like "session_user". That will require some rethinking of exactly what we want to test, whereas the intent of this patch is just to hit all the cases in which the needed renamings are cosmetic. There is no enforcement mechanism in this patch either, but if we don't add one we can expect that the tests will soon be violating the convention again. Again, that's not such a cosmetic change and it will require discussion. (But I did use a quick-hack enforcement patch to find these cases.) Discussion: <16638.1468620817@sss.pgh.pa.us>	10 years ago
Tom Lane	0426f349ef	Rearrange the handling of error context reports. ... Remove the code in plpgsql that suppressed the innermost line of CONTEXT for messages emitted by RAISE commands. That was never more than a quick backwards-compatibility hack, and it's pretty silly in cases where the RAISE is nested in several levels of function. What's more, it violated our design theory that verbosity of error reports should be controlled on the client side not the server side. To alleviate the resulting noise increase, introduce a feature in libpq and psql whereby the CONTEXT field of messages can be suppressed, either always or only for non-error messages. Printing CONTEXT for errors only is now their default behavior. The actual code changes here are pretty small, but the effects on the regression test outputs are widespread. I had to edit some of the alternative expected outputs by hand; hopefully the buildfarm will soon find anything I fat-fingered. In passing, fix up (again) the output line counts in psql's various help displays. Add some commentary about how to verify them.

Joe Conway	794e2558be	Fix sepgsql regression tests. ... The regression tests for sepgsql were broken by changes in the base distro as-shipped policies. Specifically, definition of unconfined_t in the system default policy was changed to bypass multi-category rules, which the regression test depended on. Fix that by defining a custom privileged domain (sepgsql_regtest_superuser_t) and using it instead of system's unconfined_t domain. The new sepgsql_regtest_superuser_t domain performs almost like the current unconfined_t, but restricted by multi-category policy as the traditional unconfined_t was. The custom policy module is a self defined domain, and so should not be affected by related future system policy changes. However, it still uses the unconfined_u:unconfined_r pair for selinux-user and role. Those definitions have not been changed for several years and seem less risky to rely on than the unconfined_t domain. Additionally, if we define custom user/role, they would need to be manually defined at the operating system level, adding more complexity to an already non-standard and complex regression test. Back-patch to 9.3. The regression tests will need more work before working correctly on 9.2. Starting with 9.2, sepgsql has had dependencies on libselinux versions that are only available on newer distros with the changed set of policies (e.g. RHEL 7.x). On 9.1 sepgsql works fine with the older distros with original policy set (e.g. RHEL 6.x), and on which the existing regression tests work fine. We might want eventually change 9.1 sepgsql regression tests to be more independent from the underlying OS policies, however more work will be needed to make that happen and it is not clear that it is worth the effort.
