Description:
------------
If a database contains tables with the same name in different schemas, requesting the meta data for this table returns a mix for all fields in all that tables.

The select statement use is something like
  SELECT a.attname, a.attnum, t.typname, a.attlen,
    a.attnotNULL, a.atthasdef, a.attndims
  FROM pg_class as c, pg_attribute a, pg_type t
  WHERE a.attnum > 0 AND a.attrelid = c.oid AND
    c.relname='$table' AND a.atttypid = t.oid
  ORDER BY a.attnum

but should be something like
  SELECT a.attname, a.attnum, t.typname, a.attlen,
    a.attnotNULL, a.atthasdef, a.attndims
  FROM pg_class as c, pg_attribute a, pg_type t,
      pg_namespace n
  WHERE a.attnum > 0 AND a.attrelid = c.oid AND
    c.relname='$table' AND a.atttypid = t.oid
      AND c.relnamespace=n.oid AND n.nspname='$schema'
  ORDER BY a.attnum

where $schema='public' as default
