Done. I modified the patch so that any inval in pg_foreign_server also
blows the whole plan cache.
I noticed the following addition:
+ CacheRegisterSyscacheCallback(FOREIGNDATAWRAPPEROID,
PlanCacheSysCallback, (Datum) 0);
Is that intentional? I thought you meant only to add for pg_foreign_server.
Yes, that's intentional; we would need that as well, because cached
plans might reference FDW-level options, not only server/table-level
options. I couldn't come up with regression tests for FDW-level options
in postgres_fdw, though.
