postgresql - About clustered index in postgres -

-

i'm using psql access postgres database. when viewing metadata of table, there way see whether index of table clustered index?

i heard primary key of table automatically associated clustered index, true?

note postgresql uses term "clustered index" use vaguely similar , yet different sql server.

if particular index has been nominated clustering index table, psql's \d command indicate clustered index, e.g.,

indexes:     "timezone_description_pkey" primary key, btree (timezone) cluster

postgresql not nominate indices clustering indices default. nor automatically arrange table data correlate clustered index when nominated: cluster command has used reorganise table data.
