Re: ExecRTCheckPerms() and many prunable partitions

Got this warning:

/pgsql/source/master/contrib/postgres_fdw/postgres_fdw.c: In function 'GetResultRelCheckAsUser':
/pgsql/source/master/contrib/postgres_fdw/postgres_fdw.c:1898:7: warning: unused variable 'result' [-Wunused-variable]
  Oid  result;
       ^~~~~~

I think the idea that GetRelPermissionInfo always has to scan the
complete list by OID is a nonstarter.  Maybe it would be possible to
store the list index of the PermissionInfo element in the RelOptInfo or
the RTE?  Maybe use special negative values if unknown (it knows to
search the first time) or known non-existant (probably a coding error
condition, maybe not necessary to have this)
