* Allow per-tablespace effective_io_concurrencyAlvaro Herrera2015-09-08
| | | | | | | | | | Per discussion, nowadays it is possible to have tablespaces that have wildly different I/O characteristics from others. Setting different effective_io_concurrency parameters for those has been measured to improve performance. Author: Julien Rouhaud Reviewed by: Andres Freund
* Be more conservative about removing tablespace "symlinks".Robert Haas2015-06-26
| | | | | | | | | | Don't apply rmtree(), which will gleefully remove an entire subtree, and don't even apply unlink() unless it's symlink or a directory, the only things that we expect to find. Amit Kapila, with minor tweaks by me, per extensive discussions involving Andrew Dunstan, Fujii Masao, and Heikki Linnakangas, at least some of whom also reviewed the code.
* Change many routines to return ObjectAddress rather than OIDAlvaro Herrera2015-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changed routines are mostly those that can be directly called by ProcessUtilitySlow; the intention is to make the affected object information more precise, in support for future event trigger changes. Originally it was envisioned that the OID of the affected object would be enough, and in most cases that is correct, but upon actually implementing the event trigger changes it turned out that ObjectAddress is more widely useful. Additionally, some command execution routines grew an output argument that's an object address which provides further info about the executed command. To wit: * for ALTER DOMAIN / ADD CONSTRAINT, it corresponds to the address of the new constraint * for ALTER OBJECT / SET SCHEMA, it corresponds to the address of the schema that originally contained the object. * for ALTER EXTENSION {ADD, DROP} OBJECT, it corresponds to the address of the object added to or dropped from the extension. There's no user-visible change in this commit, and no functional change either. Discussion: 20150218213255.GC6717@tamriel.snowman.net Reviewed-By: Stephen Frost, Andres Freund
* Use FLEXIBLE_ARRAY_MEMBER in a bunch more places.Tom Lane2015-02-20
| | | | | | | | | | | | | | | | Replace some bogus "x[1]" declarations with "x[FLEXIBLE_ARRAY_MEMBER]". Aside from being more self-documenting, this should help prevent bogus warnings from static code analyzers and perhaps compiler misoptimizations. This patch is just a down payment on eliminating the whole problem, but it gets rid of a lot of easy-to-fix cases. Note that the main problem with doing this is that one must no longer rely on computing sizeof(the containing struct), since the result would be compiler-dependent. Instead use offsetof(struct, lastfield). Autoconf also warns against spelling that offsetof(struct, lastfield[0]). Michael Paquier, review and additional fixes by me.

* Revamp the WAL record format.Heikki Linnakangas2014-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each WAL record now carries information about the modified relation and block(s) in a standardized format. That makes it easier to write tools that need that information, like pg_rewind, prefetching the blocks to speed up recovery, etc. There's a whole new API for building WAL records, replacing the XLogRecData chains used previously. The new API consists of XLogRegister* functions, which are called for each buffer and chunk of data that is added to the record. The new API also gives more control over when a full-page image is written, by passing flags to the XLogRegisterBuffer function. This also simplifies the XLogReadBufferForRedo() calls. The function can dig the relation and block number from the WAL record, so they no longer need to be passed as arguments. For the convenience of redo routines, XLogReader now disects each WAL record after reading it, copying the main data part and the per-block data into MAXALIGNed buffers. The data chunks are not aligned within the WAL record, but the redo routines can assume that the pointers returned by XLogRecGet* functions are. Redo routines are now passed the XLogReaderState, which contains the record in the already-disected format, instead of the plain XLogRecord. The new record format also makes the fixed size XLogRecord header smaller, by removing the xl_len field. The length of the "main data" portion is now stored at the end of the WAL record, and there's a separate header after XLogRecord for it. The alignment padding at the end of XLogRecord is also removed. This compansates for the fact that the new format would otherwise be more bulky than the old format.

* Move the backup-block logic from XLogInsert to a new file, xloginsert.c.Heikki Linnakangas2014-11-06
| | | | | | | | | | | | xlog.c is huge, this makes it a little bit smaller, which is nice. Functions related to putting together the WAL record are in xloginsert.c, and the lower level stuff for managing WAL buffers and such are in xlog.c. Also move the definition of XLogRecord to a separate header file. This causes churn in the #includes of all the files that write WAL records, and redo routines, but it avoids pulling in xlog.h into most places. Reviewed by Michael Paquier, Alvaro Herrera, Andres Freund and Amit Kapila.
* Add rmgr callback to name xlog record types for display purposes.Andres Freund2014-09-19
| | | | | | | | | | | | | | | | | | | This is primarily useful for the upcoming pg_xlogdump --stats feature, but also allows to remove some duplicated code in the rmgr_desc routines. Due to the separation and harmonization, the output of dipsplayed records changes somewhat. But since this isn't enduser oriented content that's ok. It's potentially desirable to further change pg_xlogdump's display of records. It previously wasn't possible to show the record type separately from the description forcing it to be in the last column. But that's better done in a separate commit.

* Rework 'MOVE ALL' to 'ALTER .. ALL IN TABLESPACE'Stephen Frost2014-08-21
| | | | | | | | | | | | As 'ALTER TABLESPACE .. MOVE ALL' really didn't change the tablespace but instead changed objects inside tablespaces, it made sense to rework the syntax and supporting functions to operate under the 'ALTER (TABLE|INDEX|MATERIALIZED VIEW)' syntax and to be in tablecmds.c. Pointed out by Alvaro, who also suggested the new syntax. Back-patch to 9.4.

* Add ALTER TABLESPACE ... MOVE commandStephen Frost2014-01-18
| | | | | | | | | This adds a 'MOVE' sub-command to ALTER TABLESPACE which allows moving sets of objects from one tablespace to another. This can be extremely handy and avoids a lot of error-prone scripting. ALTER TABLESPACE ... MOVE will only move objects the user owns, will notify the user if no objects were found, and can be used to move ALL objects or specific types of objects (TABLES, INDEXES, or MATERIALIZED VIEWS).

* Clean up the #include mess a little.Tom Lane2011-09-04
| | | | | | | | | | | | | | | | | walsender.h should depend on xlog.h, not vice versa. (Actually, the inclusion was circular until a couple hours ago, which was even sillier; but Bruce broke it in the expedient rather than logically correct direction.) Because of that poor decision, plus blind application of pgrminclude, we had a situation where half the system was depending on xlog.h to include such unrelated stuff as array.h and guc.h. Clean up the header inclusion, and manually revert a lot of what pgrminclude had done so things build again. This episode reinforces my feeling that pgrminclude should not be run without adult supervision. Inclusion changes in header files in particular need to be reviewed with great care. More generally, it'd be good if we had a clearer notion of module layering to dictate which headers can sanely include which others ... but that's a big task for another day.

* Generalize concept of temporary relations to "relation persistence".Robert Haas2010-12-13
| | | | | | | | | | | | | | | This commit replaces pg_class.relistemp with pg_class.relpersistence; and also modifies the RangeVar node type to carry relpersistence rather than istemp. It also removes removes rd_istemp from RelationData and instead performs the correct computation based on relpersistence. For clarity, we add three new macros: RelationNeedsWAL(), RelationUsesLocalBuffers(), and RelationUsesTempNamespace(), so that we can clarify the purpose of each check that previous depended on rd_istemp. This is intended as infrastructure for the upcoming unlogged tables patch, as well as for future possible work on global temporary tables.

| | | | | | | | | | clause implicitly whenever one is not given explicitly. Remove concept of a schema having an associated tablespace, and simplify the rules for selecting a default tablespace for a table or index. It's now just (a) explicit TABLESPACE clause; (b) default_tablespace if that's not an empty string; (c) database's default. This will allow pg_dump to use SET commands instead of tablespace clauses to determine object locations (but I didn't actually make it do so). All per recent discussions.

Also, fix heap_create to force pg_class.reltablespace to be zero instead of the database's default tablespace; this makes the world safe for CREATE DATABASE to handle all tables in the default tablespace alike, as per previous discussion. And force pg_class.reltablespace to zero when creating a relation without physical storage (eg, a view); this avoids possibly having dangling references in this column after a subsequent DROP TABLESPACE.
