Robert Haas	50533a6dc5	Support comments on FOREIGN DATA WRAPPER and SERVER objects. ... This mostly involves making it work with the objectaddress.c framework, which does most of the heavy lifting. In that vein, change GetForeignDataWrapperOidByName to get_foreign_data_wrapper_oid and GetForeignServerOidByName to get_foreign_server_oid, to match the pattern we use for other object types.

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
Robert Haas	65377e0b9c	Tighten ALTER FOREIGN TABLE .. SET DATA TYPE checks. ... If the foreign table's rowtype is being used as the type of a column in another table, we can't just up and change its data type. This was already checked for composite types and ordinary tables, but we previously failed to enforce it for foreign tables.	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
Alvaro Herrera	314288fc04	Avoid using trivial usernames in foreign_data regression test. ... Author: Martin Pihlak	16 years ago
Peter Eisentraut	8cd3755267	Tweak the regression test case so that the ordering of numbers vs. letters ... doesn't matter. This fixes failures in the Czech locale.	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
Peter Eisentraut	a5d67a0a05	Make tests pass with or without locale.	17 years ago
Peter Eisentraut	8ebf1a3d5c	Remove fairly useless mixed-case identifier test that causes locale ... dependencies.	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
