In response to Describe table and varchar lrngth  (Constantin Khatsckevich <home@const.ru>)
List pgsql-general
Here's what I came up with:

select format_type(a.atttypid, a.atttypmod) from pg_attribute a,
pg_class c where a.attrelid = c.oid and a.attname = '<field>' and
c.relname = '<relation>'

The result needs to be parsed...
