A while ago I suggested to create a backend internal function that takes
an internal type name and an atttypmod and formats it to a canonical SQL
type, to be used by pg_dump, psql, and anyone who feels like it.
I have it written now, here's an example of how it works. Any comments?
regression=# select c.relname, a.attname, format_type(t.typname, a.atttypmod)
from pg_class c, pg_attribute a, pg_type t
where c.oid=a.attrelid and t.oid=a.atttypid
and c.relname not like 'pg\_%' and a.attnum > 0
order by 1;
relname | attname | format_type
-------------------------+---------------+------------------------a | aa | texta_star
| class | character(1)a_star | aa | integera_star |
a | textabstime_tbl | f1 | abstimeaggtest | a |
smallintaggtest | b | realarrtest | a | smallint[]arrtest
| b | integer[]arrtest | c | name[]arrtest | d
| text[]arrtest | e | double precision[]arrtest | f |
character(5)[]arrtest | g | character varying(5)[]b | aa |
text
