That's because of this in heap_create_with_catalog:
/*
* Decide whether to create an array type over the relation's rowtype. We
* do not create any array types for system catalogs (ie, those made
* during initdb). We do not create them where the use of a relation as
* such is an implementation detail: toast tables, sequences and indexes.
*/
if (IsUnderPostmaster && (relkind == RELKIND_RELATION ||
relkind == RELKIND_VIEW ||
relkind == RELKIND_MATVIEW ||
relkind == RELKIND_FOREIGN_TABLE ||
relkind == RELKIND_COMPOSITE_TYPE ||
relkind == RELKIND_PARTITIONED_TABLE))
new_array_oid = AssignTypeArrayOid();
Admittedly, "!IsUnderPostmaster" is not exactly the same thing as "running
during initdb", but I do not consider this a bug. You generally should
not be using single-user mode for anything except disaster recovery.
