\r or \reset
|
|
Resets (clears) the query buffer.
|
|
\l[+] or \list[+] [ pattern ]
|
|
List the databases in the server and show their names, owners, character set encodings, and access privileges.
|
|
If pattern is specified, only databases whose names match the pattern are listed.
|
|
If + is appended to the command name, database sizes, default tablespaces, and descriptions are also displayed.
|
|
(Size information is only available for databases that the current user can connect to.)
|
|
\dg[S+] [ pattern ]
|
|
\du[S+] [ pattern ]
|
|
Lists database roles.
|
|
(Since the concepts of “users” and “groups” have been unified into “roles”, this command is now equivalent to \dg.)
|
|
By default, only user-created roles are shown; supply the S modifier to include system roles.
|
|
If pattern is specified, only those roles whose names match the pattern are listed.
|
|
If the form \du+ is used, additional information is shown about each role; currently this adds the comment for each role.
|
|
\dn[S+] [ pattern ]
|
|
Lists schemas (namespaces).
|
|
If pattern is specified, only schemas whose names match the pattern are listed.
|
|
By default, only user-created objects are shown;
|
|
supply a pattern or the S modifier to include system objects.
|
|
If + is appended to the command name, each object is listed with its associated permissions and description, if any.
|
|

In this group of commands, the letters E, i, m, s, t, and v stand for foreign table, index, materialized view, sequence, table, and view, respectively. You can specify any or
|
|
all of these letters, in any order, to obtain a listing of objects of these types. For example, \dit lists indexes and tables. If + is appended to the command name, each
|
|
object is listed with its physical size on disk and its associated description, if any. If pattern is specified, only objects whose names match the pattern are listed. By
|
|
default, only user-created objects are shown; supply a pattern or the S modifier to include system objects.

\dt <role>.*
|
|
|
|
\d[S+] [ pattern ]
|
|
For each relation (table, view, index, sequence, or foreign table) or composite type matching the pattern,
|
|
show all columns, their types, the tablespace (if not the default) and any special attributes such as NOT NULL or defaults.
|
|
Associated indexes, constraints, rules, and triggers are also shown. For foreign tables, the associated foreign server is shown as well.
|
|
("Matching the pattern" is defined in Patterns below.)
|
|
For some types of relation, \d shows additional information for each column: column values for sequences,
|
|
indexed expression for indexes and foreign data wrapper options for foreign tables.
|
|
|
|
The command form \d+ is identical, except that more information is displayed: any comments associated with the columns of the table are shown,
|
|
as is the presence of OIDs in the table, the view definition if the relation is a view, a non-default replica identity setting.
|
|
|
|
By default, only user-created objects are shown; supply a pattern or the S modifier to include system objects.
|
|
|
|
Note: If \d is used without a pattern argument, it is equivalent to \dtvsE which will show a list of all visible tables, views, sequences and foreign tables.
|
|
This is purely a convenience measure.
