I just ran create table tomlist as select your query and create table
dimlist as select my query, then:

dim=# select * from tomlist except select * from dimlist;                                              desc

foraccess method btree;ALTER EXTENSION hstore ADD operator class @extschema@.hash_hstore_ops for access method hash;
 
(9 rows)

No difference on @extschema@ use here.

dim=# select t.desc, d.desc from tomlist t natural join dimlist d limit 1;
-[ RECORD 1 ]---------------------------------------------
desc | ALTER EXTENSION hstore ADD type @extschema@.hstore;
desc | ALTER EXTENSION hstore ADD type @extschema@.hstore;

dim=# select t.desc, d.desc from tomlist t natural join dimlist d limit 1 offset 10;
-[ RECORD 1 ]---------------------------------------------------------------------------
desc | ALTER EXTENSION hstore ADD function @extschema@.slice(@extschema@.hstore,text[]);
desc | ALTER EXTENSION hstore ADD function @extschema@.slice(@extschema@.hstore,text[]);
