My DB version(): PostgreSQL 10.3 (Ubuntu 10.3-1.pgdg14.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 4.8.4-2ubuntu1~14.04.4) 4.8.4, 64-bit
Supposing I have a foreign table F and a view V that selects rows from F.
The owner of F is USER1.
The owner of V is USER2.
The currently logged user is "me".
When I query the foreign table F, the DBMS engine looks for USER MAPPING for "me", regardless of who is the owner of the table.
When I query the view V, the engine searches the USER MAPPING for USER2 who is the owner of the view.
This looks inconsistent and misleading. I wonder, are there any reasons behind this design decision? Is it documented somewhere (I did not find it)?

Vlad
