Ordinarily we can omit checking of a WHERE condition that matches a partial index's condition, when we are using an indexscan on that partial index. However, in SELECT FOR UPDATE we must include the "redundant" filter condition in the plan so that it gets checked properly in an EvalPlanQual recheck. The planner got this mostly right, but improperly omitted the filter condition if the index in question was on an inheritance child table. In READ COMMITTED mode, this could result in incorrectly returning just-updated rows that no longer satisfy the filter condition. The cause of the error is using get_parse_rowmark() when get_plan_rowmark() is what should be used during planning. In 9.3 and up, also fix the same mistake in contrib/postgres_fdw. It's currently harmless there (for lack of inheritance support) but wrong is wrong, and the incorrect code might get copied to someplace where it's more significant. Report and fix by Kyotaro Horiguchi. Back-patch to all supported branches. |

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "gmake all" and "gmake
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
