Thread: SQL/MED - FDW API

SQL/MED - FDW API

From
Shigeru HANADA
Date:
Attached are WIP version of patches for FDW API.  Basically not
changed from last version but rebased to current HEAD.

To make review easier, I split core functionality into 3 patches.
Please apply these patches in the following order.

1) fdw_handler - this patch adds HANDLER option to both syntax and
catalog of FOREIGN DATA WRAPPER.

2) foreign_scan - this patch adds following: ForeignScan executor-node,
hooks in planner and executor, and FdwRoutine (FDW API).

3) catalog_lookup - this patch adds GetForeignTable() whicch returns
ForeignTable object, similar to GetForeignDataWrapper(),
GetForeignServer(), and GetUserMapping().  This function is assumed to
be used by FDWs.

You would be able to test these patches with file_fdw wrapper which
would be posted in another thread.

Regards,

wrapper patches which will be posted in another thread.
