description.description as comment

You can receive column comments in SQL:

SELECT a.attname AS column, d.description AS COMMENT
FROM pg_class c
JOIN pg_description d ON c.oid=d.objoid
JOIN pg_attribute a ON c.oid = a.attrelid
WHERE c.relname='monitors'
AND a.attnum = d.objsubid

For those coming from MySQL:
SHOW TABLES = d
SHOW DATABASES = l
SHOW COLUMNS = d table

However the * commands only work in psql and not via other interfaces, such as queries via PHP. Similar data can be retrieved with the following SQL commands:

So in the psql console type
l to see the databases,
d ....

SHOW TABLES (d) = SELECT table_name FROM information_schema.tables WHERE table_schema = 'public'

SHOW DATABASES (l) = SELECT datname FROM pg_database;

SHOW COLUMNS FROM table (d table) = SELECT column_name FROM information_schema.columns WHERE table_name ='table';

This works for me:

select pg_class.relname, pg_attribute.attname, pg_type.typname from pg_class, pg_attribute, pg_type where pg_class.relname = 'YOURTABLENAME' and pg_class.oid = pg_attribute.attrelid and pg_type.oid = pg_attribute.atttypid having attnum > 0

Is there any equivalent form for this in SQL?
