I finally managed to sort out all needed permissions and mappings. Thanks for all replies!

[ shrug... ] WFM; if I can select from the foreign table then I can make a materialized view that selects from it, and that refreshes without complaint. Admittedly, getting things set up to select from the foreign table is trickier than it sounds: your local user needs SELECT on the foreign table plus a mapping to some remote userid, and *on the remote server* that remote userid needs SELECT on whatever the foreign table is referencing. I'm guessing you messed up one of these components. regards, tom lane Hendrik, perhaps an easy way to check out Tom's suggestion is to create a very simple materialized view that selects just from one of the foreign tables, then attempt the REFRESH. If that works, then keep adding more tables from your original materialized view until you have found the problem. Basically, reduce the problem to the simplest case, and if that works, then keep adding to it until you hit the problem. You may still not know why the problem is happening, but you'll at least know where to focus any further investigation.
