Objects in an extension are shippable to a foreign server if the extension is part of the foreign server definition's shippable extensions list. But this was not properly considered in some cases when checking whether a join condition can be pushed to a foreign server and the join condition uses an object from a shippable extension. So the join would never be pushed down in those cases. So, the list of extensions needs to be made available in fpinfo of the relation being considered to be pushed down before any expressions are assessed for being shippable. Fix foreign_join_ok() to do that for a join relation. The code to save FDW options in fpinfo is scattered at multiple places. Bring all of that together into functions apply_server_options(), apply_table_options(), and merge_fdw_options(). David Rowley and Ashutosh Bapat, per report from David Rowley |

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 "make all" and "make 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.
