Tom Lane	327e025071	Create the catalog infrastructure for foreign-data-wrapper handlers. Add a fdwhandler column to pg_foreign_data_wrapper, plus HANDLER options in the CREATE FOREIGN DATA WRAPPER and ALTER FOREIGN DATA WRAPPER commands, plus pg_dump support for same. Also invent a new pseudotype fdw_handler with properties similar to language_handler. This is split out of the "FDW API" patch for ease of review; it's all stuff we will certainly need, regardless of any other details of the FDW API. FDW handler functions will not actually get called yet. In passing, fix some omissions and infelicities in foreigncmds.c. Shigeru Hanada, Jan Urbanski, Heikki Linnakangas	15 years ago
Tom Lane	d9572c4e3b	Core support for "extensions", which are packages of SQL objects. This patch adds the server infrastructure to support extensions. There is still one significant loose end, namely how to make it play nice with pg_upgrade, so I am not yet committing the changes that would make all the contrib modules depend on this feature. In passing, fix a disturbingly large amount of breakage in AlterObjectNamespace() and callers.

Heikki Linnakangas	8aea1373d8	Don't require usage privileges on the foreign data wrapper when creating a foreign table. We check for usage privileges on the foreign server, that ought to be enough. Shigeru HANADA	15 years ago
Robert Haas	0d692a0dc9	Basic foreign table support. Foreign tables are a core component of SQL/MED. This commit does not provide a working SQL/MED infrastructure, because foreign tables cannot yet be queried. Support for foreign table scans will need to be added in a future patch. However, this patch creates the necessary system catalog structure, syntax support, and support for ancillary operations such as COMMENT and SECURITY LABEL. Shigeru Hanada, heavily revised by Robert Haas	15 years ago

Robert Haas	cc1ed40d57	Object access hook framework, with post-creation hook. After a SQL object is created, we provide an opportunity for security or logging plugins to get control; for example, a security label provider could use this to assign an initial security label to newly created objects. The basic infrastructure is (hopefully) reusable for other types of events that might require similar treatment. KaiGai Kohei, with minor adjustments.	15 years ago

Robert Haas	2a6ef3445c	Standardize get_whatever_oid functions for object types with unqualified names. - Add a missing_ok parameter to get_tablespace_oid. - Avoid duplicating get_tablespace_od guts in objectNamesToOids. - Add a missing_ok parameter to get_database_oid. - Replace get_roleid and get_role_checked with get_role_oid. - Add get_namespace_oid, get_language_oid, get_am_oid. - Refactor existing code to use new interfaces. Thanks to KaiGai Kohei for the review.	15 years ago
Robert Haas	e26c539e9f	Wrap calls to SearchSysCache and related functions using macros. The purpose of this change is to eliminate the need for every caller of SearchSysCache, SearchSysCacheCopy, SearchSysCacheExists, GetSysCacheOid, and SearchSysCacheList to know the maximum number of allowable keys for a syscache entry (currently 4). This will make it far easier to increase the maximum number of keys in a future release should we choose to do so, and it makes the code shorter, too. Design and review by Tom Lane.	16 years ago

Heikki Linnakangas	4e766f2d17	Always pass catalog id to the options validator function specified in CREATE FOREIGN DATA WRAPPER. Arguably it wasn't a bug because the documentation said that it's passed the catalog ID or zero, but surely we should provide it when it's known. And there isn't currently any scenario where it's not known, and I can't imagine having one in the future either, so better remove the "or zero" escape hatch and always pass a valid catalog ID. Backpatch to 8.4. Martin Pihlak	16 years ago

Tom Lane	090173a3f9	Remove the recently added node types ReloptElem and OptionDefElem in favor of adding optional namespace and action fields to DefElem. Having three node types that do essentially the same thing bloats the code and leads to errors of confusion, such as in yesterday's bug report from Khee Chin.	17 years ago
Peter Eisentraut	7babccb915	Add the possibility to specify an explicit validator function for foreign-data wrappers (similar to procedural languages). This way we don't need to retain the nearly empty libraries, and we are more free in how to implement the wrapper API in the future.	17 years ago
Peter Eisentraut	93a6be63a5	Revise the permission checking on user mapping DDL commands. CREATE/ALTER/DROP USER MAPPING are now allowed either by the server owner or by a user with USAGE privileges for his own user name. This is more or less what the SQL standard wants anyway (plus "implementation-defined") Hide information_schema.user_mapping_options.option_value, unless the current user is the one associated with the user mapping, or is the server owner and the mapping is for PUBLIC, or is a superuser. This is to protect passwords. Also, fix a bug in information_schema._pg_foreign_servers, which hid servers using wrappers where the current user did not have privileges on the wrapper. The correct behavior is to hide servers where the current user has no privileges on the server.	17 years ago

Tom Lane	a1212d09a1	Fix various confusions of pointers and OIDs, unsafe assumptions about nulls, etc. I think this will fix the current buildfarm issues ...	17 years ago
Heikki Linnakangas	cef8efc62d	Don't use OidIsValid to check the return value of transformGenericOptions, because transformGenericOptions returns an array, not an Oid. I'm not sure if this fixes the crashes seen in buildfarm, but it should be fixed anyway.	17 years ago
Peter Eisentraut	cae565e503	SQL/MED catalog manipulation facilities This doesn't do any remote or external things yet, but it gives modules like plproxy and dblink a standardized and future-proof system for managing their connection information. Martin Pihlak and Peter Eisentraut	17 years ago
