I meant to speak of RELKIND_PARTITIONED_TABLE tables as having partitions
(although it could be a partition itself too).  If based on the relkind,
we had shown their type as "partitioned table" (not just "table"), then we
wouldn't need a separate flag/column in the \d output to distinguish
partitioned tables as being different from regular tables, as Craig seemed
to be proposing.

Since we are going the route of showing relispartition = true relations as
of different type in the \d listing (as "partition"/"foreign partition"),
we might as well go and spell RELKIND_PARTITIONED_TABLE tables as
"partitioned table".  But, I'm afraid that it would be a much bigger
change if we don't want to restrict this terminology change to \d listing;
error messages don't bother about distinguishing "partitions"
(relispartition = true) or "partitioned tables"
