First, your query is incorrect: on my test DB is returns 156 rows for
12 (non PK) indexes on a table.

Second, you must enclose unregular table names into either simple &
double quotes and use the same kinda query as '\d+ mytable':

SELECT c2.relname, i.indisprimary, i.indisunique, i.indisclustered,
    i.indisvalid, pg_catalog.pg_get_indexdef(i.indexrelid, 0, true),
      pg_catalog.pg_get_constraintdef(con.oid, true), contype,
    condeferrable, condeferred, c2.reltablespace
FROM pg_catalog.pg_class c, pg_catalog.pg_class c2, pg_catalog.pg_index i
      LEFT JOIN pg_catalog.pg_constraint con ON
    (conrelid = i.indrelid
    AND conindid = i.indexrelid
    AND contype IN ('p','u','x'))
WHERE c.oid = '"MyUnregularlyNamedTABLE"'::regclass::oid
    AND c.oid = i.indrelid
    AND i.indexrelid = c2.oid
    AND i.indisprimary = 'f'
ORDER BY i.indisprimary DESC, i.indisunique DESC, c2.relname;

(also work with regular names).
