Alvaro Herrera	2f9eb31320	pg_dump: Allow dumping data of specific foreign servers ... The new command-line switch --include-foreign-data=PATTERN lets the user specify foreign servers from which to dump foreign table data. This can be refined by further inclusion/exclusion switches, so that the user has full control over which tables to dump. A limitation is that this doesn't work in combination with parallel dumps, for implementation reasons. This might be lifted in the future, but requires shuffling some code around.

Peter Eisentraut	cc8d415117	Unified logging system for command-line programs ... This unifies the various ad hoc logging (message printing, error printing) systems used throughout the command-line programs. Features: - Program name is automatically prefixed. - Message string does not end with newline. This removes a common source of inconsistencies and omissions. - Additionally, a final newline is automatically stripped, simplifying use of PQerrorMessage() etc., another common source of mistakes. - I converted error message strings to use %m where possible. - As a result of the above several points, more translatable message strings can be shared between different components and between frontends and backend, without gratuitous punctuation or whitespace differences. - There is support for setting a "log level". This is not meant to be user-facing, but can be used internally to implement debug or verbose modes. - Lazy argument evaluation, so no significant overhead if logging at some level is disabled. - Some color in the messages, similar to gcc and clang. Set PG_COLOR=auto to try it out. Some colors are predefined, but can be customized by setting PG_COLORS. - Common files (common/, fe_utils/, etc.) can handle logging much more simply by just using one API without worrying too much about the context of the calling program, requiring callbacks, or having to pass "progname" around everywhere. - Some programs called setvbuf() to make sure that stderr is unbuffered, even on Windows. But not all programs did that. This is now done centrally. Soft goals: - Reduces vertical space use and visual complexity of error reporting in the source code. - Encourages more deliberate classification of messages. For example, in some cases it wasn't clear without analyzing the surrounding code whether a message was meant as an error or just an info. - Concepts and terms are vaguely aligned with popular logging frameworks such as log4j and Python logging. This is all just about printing stuff out. Nothing affects program flow (e.g., fatal exits). The uses are just too varied to do that. Some existing code had wrappers that do some kind of print-and-exit, and I adapted those. I tried to keep the output mostly the same, but there is a lot of historical baggage to unwind and special cases to consider, and I might not always have succeeded. One significant change is that pg_rewind used to write all error messages to stdout. That is now changed to stderr.

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.

Michael Paquier	c34bca9ea5	Consolidate cross-option checks in pg_restore ... This moves one check for conflicting options from the archive restore code to the main function where other similar checks are performed. Also reword the error message to be consistent with other messages. The only option combination impacted is --create specified with --single-transaction, and informing the caller at an early step saves from opening the archive worked on. A TAP test is added for this combination. Author: Daniel Gustafsson Reviewed-by: Fabien Coelho Discussion: https://postgr.es/m/616808BD-4B59-4E6C-97A9-7317F62D5570@yesql.se	7 years ago

Stephen Frost	31a8b77a92	Improve pg_dump regression tests and code coverage ... These improvements bring the lines-of-code coverage of pg_dump.c up to 87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly every function is covered, three of the four which aren't are only called when talking to older PG instances. There is more which can, and should, be done here to improve the coverage but it's past time to see what the buildfarm thinks of this. What has been added: - Coverage for many more command-line options - Use command_fails_like instead of command_exit_is - Operator classes, operator families - Text search configuration, templates, parsers, dictionaries - FDWs, servers, foreign tables - Materialized views - Improved Publications / Subscriptions test (though this needs work, see PG10 open items and tests marked with XXX in 002_pg_dump.pl) - Unlogged tables - Partitioned tables - Additional ACL testing for various object types There is room for improvement, specifically: - Various type-based option (alignment, storage, etc) - Composite type collation - Extra Procedural language functions (inline, validator) - Different function options (SRF, Transform, config, security definer, cost, leakproof) - OpClass options (default, storage, order by, recheck) - OpFamily options (order by, recheck) - Aggregate functions (combinefunc, serialfunc, deserialfunc, etc) - Text Search parser 'headline' - Text Search template 'init' - FDW options (handler, validator, options) - Server options (type, version, options) - User mapping options - Default ACLs for sequences, types - Security labels - View circular dependencies (last function that needs coverage) - Toast table autovacuum options - Replica identity options - Independent indexes (plus marking them as clustered on) - Deferrable / initially deferred constraints - Independent domain constraints There's bits of extension pg_dump'ing also not covered, but those will need to go into test_pg_dump (such as having a filter for config tables). Last, but not least, this approximately halves the number of tests run with 'ok()' by removing the ok()-based checking of if all runs are covered by each test. Instead, 002_pg_dump.pl will just exit out in such a case (with a message in the log file). In general, when adding tests, cover all runs unless there is a very good reason not to (such as adding a 'catch-all' case). With these changes, the resulting output and number of "tests" run is actually reduced.	9 years ago

Stephen Frost	6bd356c33a	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.	10 years ago
