Start psql with the -E option, and you can see all the internally
generated queries. E.g (ex1_tup is a composite type):
psql -E regression
[snipped all the startup stuff]
regression=# \d ex1_tup
********* QUERY **********
SELECT c.oid, n.nspname, c.relname
FROM pg_catalog.pg_class c LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE pg_catalog.pg_table_is_visible(c.oid) AND c.relname ~ '^ex1_tup$'
ORDER BY 2, 3;
**************************
********* QUERY **********
SELECT relhasindex, relkind, relchecks, reltriggers, relhasrules
FROM pg_catalog.pg_class WHERE oid = '1336877'
**************************
********* QUERY **********
SELECT a.attname, pg_catalog.format_type(a.atttypid, a.atttypmod), (SELECT substring(d.adsrc for 128) FROM
pg_catalog.pg_attrdefd WHERE d.adrelid = a.attrelid AND d.adnum = a.attnum AND a.atthasdef), a.attnotnull, a.attnum
FROM pg_catalog.pg_attribute a
WHERE a.attrelid = '1336877' AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
