An even easier way to see what queries psql emits for its backslash
commands is to start psql with -E option, then do the backslash
commands. This gives me, for example,
regression=# \l
********* QUERY **********
SELECT pg_database.datname as "Database",
pg_user.usename as "Owner"FROM pg_database, pg_user
WHERE pg_database.datdba = pg_user.usesysid
UNION
SELECT pg_database.datname as "Database",
NULL as "Owner"FROM pg_database
WHERE pg_database.datdba NOT IN (SELECT usesysid FROM pg_user)
ORDER BY "Database"
**************************
List of databases
Database | Owner
------------+----------
regression | postgres
template0 | postgres
template1 | postgres
(3 rows)
regression=#
