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.

|
|
* NOTES
|
|
* Path nodes do not have any readfuncs support, because we never
|
|
* have occasion to read them in. (There was once code here that
|
|
* claimed to read them, but it was broken as well as unused.) We
|
|
* never read executor state trees, either.
|
|
*
|
|
* Parse location fields are written out by outfuncs.c, but only for
|
|
* possible debugging use. When reading a location field, we discard
|
|
* the stored value and set the location field to -1 (ie, "unknown").
|
|
* This is because nodes coming from a stored rule should not be thought
|
|
* to have a known location in the current query's text.
