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.

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.

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.

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.

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.

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.

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.

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.

Tom Lane a1212d09a1 Fix various confusions of pointers and OIDs, unsafe assumptions about nulls,
etc.  I think this will fix the current buildfarm issues ...

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.

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.
