Get the default values of table columns in Postgres?

Question

I\'m looking for a way to run a query to find the default values of the columns of a table in Postgres. For example, if I made a table with the following query:

Answer 1

Use the information schema:

SELECT column_name, column_default
FROM information_schema.columns
WHERE (table_schema, table_name) = ('public', 'mytable')
ORDER BY ordinal_position;

 column_name │             column_default             
─────────────┼────────────────────────────────────────
 integer     │ 2
 text        │ 'I am default'::character varying
 moretext    │ 'I am also default'::character varying
 unimportant │ 
(4 rows)

Up to the schema naming, this should work in any SQL database system.
