try starting psql with the -E option -- this displays all queries used
internally to the screen, i.e.:
bash-2.04$ psql -E
********* QUERY *********
SELECT usesuper FROM pg_user WHERE usename = 'mfork'
*************************
Welcome to psql, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit
mfork=# \d test
********* QUERY *********
SELECT relhasindex, relkind, relchecks, reltriggers, relhasrules
FROM pg_class WHERE relname='test'
*************************
********* QUERY *********
SELECT a.attname, t.typname, a.attlen, a.atttypmod, a.attnotnull,
a.atthasdef, a.attnum
FROM pg_class c, pg_attribute a, pg_type t
WHERE c.relname = 'test'
AND a.attnum > 0 AND a.attrelid = c.oid AND a.atttypid = t.oid
ORDER BY a.attnum
*************************
Table "test"
Attribute | Type | Modifier
-----------+------+----------
t | text |
d | date |
So to get the info displayed with \d, execute the query:
SELECT a.attname, t.typname, a.attlen, a.atttypmod, a.attnotnull,
a.atthasdef, a.attnum
FROM pg_class c, pg_attribute a, pg_type t
WHERE c.relname = '<<TABLE NAME>>'
AND a.attnum > 0 AND a.attrelid = c.oid AND a.atttypid = t.oid
ORDER BY a.attnum
