Previously, the foreign join pushdown infrastructure left the question of security entirely up to individual FDWs, but it would be easy for a foreign data wrapper to inadvertently open up subtle security holes that way. So, make it the core code's job to determine which user mapping OID is relevant, and don't attempt join pushdown unless it's the same for all relevant relations. Per a suggestion from Tom Lane. Shigeru Hanada and Ashutosh Bapat, reviewed by Etsuro Fujita and KaiGai Kohei, with some further changes by me. |
