This will give the comment on your table and any column:
SELECT DISTINCT ON (c.relname)
n.nspname as schema,
c.relname,
a.rolname as owner,
0 as col_seq,
'' as column,
d.description as comment
FROM pg_class c
LEFT JOIN pg_attribute col ON (col.attrelid = c.oid)
LEFT JOIN pg_description d ON (d.objoid = col.attrelid AND d.objsubid = 0)
JOIN pg_namespace n ON (n.oid = c.relnamespace)
JOIN pg_authid a ON ( a.OID = c.relowner )
WHERE n.nspname NOT LIKE 'information%'
AND relname NOT LIKE 'pg_%'
AND relname NOT LIKE 'information%'
AND relname NOT LIKE 'sql_%'
AND relname = 'articlestats'
AND relkind = 'r'
AND d.description IS NOT NULL
UNION
SELECT n.nspname as schema,
c.relname,
'' as owner,
col.attnum as col_seq,
col.attname as column,
d.description
FROM pg_class c
JOIN pg_attribute col ON (col.attrelid = c.oid)
LEFT JOIN pg_description d ON (d.objoid = col.attrelid AND d.objsubid =
