Hm ... I reproduced the problem here. I can't see anything that looks
wrong about the pg_depend entries:
obj | ref
| deptype
----------------------------------------+-------------------------------------------------------+---------
extension deptestext | schema public
| n
composite type droppabletype1 | type droppabletype1
| i
type droppabletype1[] | type droppabletype1
| i
type droppabletype1 | schema public
| n
type droppabletype1 | extension deptestext
| e
table testtable | schema public
| n
table testtable | extension deptestext
| e
table testtable column droppablecol2 | type droppabletype1
| n
table testtable column droppablecol1 | type droppabletype1
| n
table testtable column undroppablecol1 | type undroppabletype
| n
table testtable column undroppablecol2 | type undroppabletype
| n
type testtable[] | type testtable
| i
type testtable | table testtable
| i
composite type undroppabletype | type undroppabletype
| i
type undroppabletype[] | type undroppabletype
| i
type undroppabletype | schema public
| n
type undroppabletype | extension deptestext
| e
toast table pg_toast.pg_toast_162813 | table testtable
| i
type pg_toast.pg_toast_162813 | toast table pg_toast.pg_toast_162813
| i
index pg_toast.pg_toast_162813_index | toast table pg_toast.pg_toast_162813
column chunk_id | a
index pg_toast.pg_toast_162813_index | toast table pg_toast.pg_toast_162813
column chunk_seq | a
(21 rows)
but sure enough:
d1=# drop extension deptestext;
ERROR: cannot drop extension deptestext because other objects depend on it
DETAIL: table testtable column undroppablecol2 depends on type undroppabletype
table testtable column undroppablecol1 depends on type undroppabletype
HINT: Use DROP ... CASCADE to drop the dependent objects too.
I suspect this is actually a bug in the dependency search logic in DROP.
Don't have the energy to chase it right now though.
