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
--------------------------------------------------------------------------------------------------
ALTER EXTENSION hstore ADD operator family @extschema@.gin_hstore_ops for
access method gin;
ALTER EXTENSION hstore ADD operator class @extschema@.btree_hstore_ops for
access method btree;
ALTER EXTENSION hstore ADD operator family @extschema@.hash_hstore_ops for
access method hash;
ALTER EXTENSION hstore ADD operator class @extschema@.gist_hstore_ops for
access method gist;
ALTER EXTENSION hstore ADD operator family @extschema@.gist_hstore_ops for
access method gist;
ALTER EXTENSION hstore ADD cast from text[] to @extschema@.hstore;
ALTER EXTENSION hstore ADD operator class @extschema@.gin_hstore_ops for
access method gin;
ALTER EXTENSION hstore ADD operator family @extschema@.btree_hstore_ops for
access 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[]);
