Precedence: bulk

Running this query:

draft=3D# SELECT DISTINCT column_name, data_type,
character_maximum_length, character_octet_length, numeric_precision,
numeric_precision_radix, numeric_scale, is_nullabl
e, column_default, ordinal_position, CASE WHEN column_name IN (SELECT
ccu.column_name FROM information_schema.constraint_column_usage ccu,
information_schema.table_con
straints tc WHERE ccu.constraint_name =3D tc.constraint_name AND
tc.constraint_type =3D 'PRIMARY KEY' AND ccu.table_name =3D 'leagues' )
THEN 'YES' ELSE 'NO' END AS is_pk  F
ROM information_schema.columns WHERE table_name=3D'leagues' ORDER BY
ordinal_position;


still produces good results:

column_name  |     data_type     | character_maximum_length |
character_octet_length | numeric_precision | numeric_precision_radix |
numeric_scale | is_nullable | col
umn_default | ordinal_position | is_pk
