I think you're saying you want it as a single JSON *array*, right? An
object of objects doesn't make sense. Assuming that's right, this seems
to work:
db1=# select json_agg(schemata) from schemata;
json_agg
----------------------------------------------------------------------------------------------------------
[{"catalog_name":"db1","schema_name":"information_schema","schema_name_address":"/information_schema"},
{"catalog_name":"db1","schema_name":"pg_catalog","schema_name_address":"/pg_catalog"},
{"catalog_name":"db1","schema_name":"pg_temp_1","schema_name_address":"/pg_temp_1"},
{"catalog_name":"db1","schema_name":"pg_toast","schema_name_address":"/pg_toast"},
{"catalog_name":"db1","schema_name":"pg_toast_temp_1","schema_name_address":"/pg_toast_temp_1"},
{"catalog_name":"db1","schema_name":"public","schema_name_address":"/public"}]
