pg_dumpall [connection-option...] [option...]

-a
--data-only

Dump only the data, not the schema (data definitions).

-c
--clean

Include SQL commands to clean (drop) databases before recreating them.DROP commands for roles and tablespaces are added as well.

-ffilename
--file=filename

Send output to the specified file. If this is omitted, the standard output is used.

-g
--globals-only

Dump only global objects (roles and tablespaces), no databases.

-o
--oids

Dump object identifiers (OIDs) as part of the data for every table. Use this option if your application references theOID columns in some way (e.g., in a foreign key constraint). Otherwise, this option should not be used.

-O
--no-owner

Do not output commands to set ownership of objects to match the original database. By default,pg_dumpall issuesALTER OWNER orSET SESSION AUTHORIZATION statements to set ownership of created schema elements. These statements will fail when the script is run unless it is started by a superuser (or the same user that owns all of the objects in the script). To make a script that can be restored by any user, but will give that user ownership of all the objects, specify-O.

-r
--roles-only

Dump only roles, no databases or tablespaces.

-s
--schema-only

Dump only the object definitions (schema), not data.

-Susername
--superuser=username

Specify the superuser user name to use when disabling triggers. This is relevant only if--disable-triggers is used. (Usually, it's better to leave this out, and instead start the resulting script as superuser.)

-t
--tablespaces-only

Dump only tablespaces, no databases or roles.

-v
--verbose

Specifies verbose mode. This will causepg_dumpall to output start/stop times to the dump file, and progress messages to standard error. It will also enable verbose output inpg_dump.

-V
--version

Print thepg_dumpall version and exit.

-x
--no-privileges
--no-acl

Prevent dumping of access privileges (grant/revoke commands).

--binary-upgrade

This option is for use by in-place upgrade utilities. Its use for other purposes is not recommended or supported. The behavior of the option may change in future releases without notice.

--column-inserts
--attribute-inserts

Dump data asINSERT commands with explicit column names (INSERT INTOtable (column, ...) VALUES ...). This will make restoration very slow; it is mainly useful for making dumps that can be loaded into non-Postgres Pro databases.

--disable-dollar-quoting

This option disables the use of dollar quoting for function bodies, and forces them to be quoted using SQL standard string syntax.

--disable-triggers

This option is relevant only when creating a data-only dump. It instructspg_dumpall to include commands to temporarily disable triggers on the target tables while the data is reloaded. Use this if you have referential integrity checks or other triggers on the tables that you do not want to invoke during data reload.

Presently, the commands emitted for--disable-triggers must be done as superuser. So, you should also specify a superuser name with-S, or preferably be careful to start the resulting script as a superuser.

--if-exists

Use conditional commands (i.e. add anIF EXISTS clause) to clean databases and other objects. This option is not valid unless--clean is also specified.

--inserts

Dump data asINSERT commands (rather thanCOPY). This will make restoration very slow; it is mainly useful for making dumps that can be loaded into non-Postgres Pro databases. Note that the restore might fail altogether if you have rearranged column order. The--column-inserts option is safer, though even slower.

--lock-wait-timeout=timeout

Do not wait forever to acquire shared table locks at the beginning of the dump. Instead, fail if unable to lock a table within the specifiedtimeout. The timeout may be specified in any of the formats accepted bySET statement_timeout. Allowed values vary depending on the server version you are dumping from, but an integer number of milliseconds is accepted by all versions since 7.3. This option is ignored when dumping from a pre-7.3 server.

--no-security-labels

Do not dump security labels.

--no-tablespaces

Do not output commands to create tablespaces nor select tablespaces for objects. With this option, all objects will be created in whichever tablespace is the default during restore.

--no-unlogged-table-data

Do not dump the contents of unlogged tables. This option has no effect on whether or not the table definitions (schema) are dumped; it only suppresses dumping the table data.

--quote-all-identifiers

Force quoting of all identifiers. This option is recommended when dumping a database from a server whosePostgreSQL major version is different frompg_dumpall's, or when the output is intended to be loaded into a server of a different major version. By default,pg_dumpall quotes only identifiers that are reserved words in its own major version. This sometimes results in compatibility issues when dealing with servers of other versions that may have slightly different sets of reserved words. Using--quote-all-identifiers prevents such issues, at the price of a harder-to-read dump script.

--use-set-session-authorization

Output SQL-standardSET SESSION AUTHORIZATION commands instead ofALTER OWNER commands to determine object ownership. This makes the dump more standards compatible, but depending on the history of the objects in the dump, might not restore properly.

-?
--help

Show help aboutpg_dumpall command line arguments, and exit.

-dconnstr
--dbname=connstr

Specifies parameters used to connect to the server, as a connection string. SeeSection 31.1.1 for more information.

The option is called--dbname for consistency with other client applications, but becausepg_dumpall needs to connect to many databases, database name in the connection string will be ignored. Use-l option to specify the name of the database used to dump global objects and to discover what other databases should be dumped.

-hhost
--host=host

Specifies the host name of the machine on which the database server is running. If the value begins with a slash, it is used as the directory for the Unix domain socket. The default is taken from thePGHOST environment variable, if set, else a Unix domain socket connection is attempted.

-ldbname
--database=dbname

Specifies the name of the database to connect to for dumping global objects and discovering what other databases should be dumped. If not specified, thepostgres database will be used, and if that does not exist,template1 will be used.

-pport
--port=port

Specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections. Defaults to thePGPORT environment variable, if set, or a compiled-in default.

-Uusername
--username=username

User name to connect as.

-w
--no-password

Never issue a password prompt. If the server requires password authentication and a password is not available by other means such as a.pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user is present to enter a password.

-W
--password

Forcepg_dumpall to prompt for a password before connecting to a database.

This option is never essential, sincepg_dumpall will automatically prompt for a password if the server demands password authentication. However,pg_dumpall will waste a connection attempt finding out that the server wants a password. In some cases it is worth typing-W to avoid the extra connection attempt.

Note that the password prompt will occur again for each database to be dumped. Usually, it's better to set up a~/.pgpass file than to rely on manual password entry.

--role=rolename

Specifies a role name to be used to create the dump. This option causespg_dumpall to issue aSET ROLErolename command after connecting to the database. It is useful when the authenticated user (specified by-U) lacks privileges needed bypg_dumpall, but can switch to a role with the required rights. Some installations have a policy against logging in directly as a superuser, and use of this option allows dumps to be made without violating the policy.
