For 9.1 and 9.0, you can get foreign table's oid as the first parameter of PlanForeignScan function. For 9.2, you can get it as the third parameter of GetForeignRelSize, GetForeignPaths, and GetForeignPlan functions. In other functions, calling RelationGetRelid(ForeignScanState->ss.ss_currentRelation) returns the oid of the foreign table. Once you obtained oid of a foreign table, you can get the name of the foreign table by calling get_rel_name function with the oid, as same as ordinary tables.
