pg_dumpall

Dump only the data, not the schema (data definitions). This option is only meaningful for the plain-text format. For the archive formats, you may specify the option when you call pg_restore.

Output commands to clean (drop) database objects prior to (the commands for) creating them. This option is only meaningful for the plain-text format. For the archive formats, you may specify the option when you call pg_restore.

Send output to the specified file.

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

Dump object identifiers (OIDs) as part of the data for every table. Use of this option is not recommended for files that are intended to be restored into Greengage DB.

Do not output commands to set ownership of objects to match the original database. By default, pg_dump issues ALTER OWNER or SET SESSION AUTHORIZATION statements to set ownership of created database objects. 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. This option is only meaningful for the plain-text format. For the archive formats, you may specify the option when you call pg_restore.

Dump only roles, not databases or tablespaces.

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

Specify the superuser user name to use when deactivating triggers. This is relevant only if --disable-triggers is used. It is better to leave this out, and instead start the resulting script as a superuser.

Dump only tablespaces, not databases or roles.

Specify verbose mode. This will cause pg_dump to output detailed object comments and start/stop times to the dump file, and progress messages to standard error.

Print the pg_dumpall version and exit.

Prevent dumping of access privileges (GRANT/REVOKE commands).

This option is for use by in-place upgrade utilities. Its use for other purposes is not recommended or supported.

Dump data as INSERT commands with explicit column names (INSERT INTO <table> (<column>, …​) VALUES …​). This will make restoration very slow; it is mainly useful for making dumps that can be loaded into non-PostgreSQL-based databases. Also, since this option generates a separate command for each row, an error in reloading a row causes only that row to be lost rather than the entire table contents.

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

This option is relevant only when creating a data-only dump. It instructs pg_dumpall to include commands to temporarily deactivate triggers on the target tables while the data is reloaded. Use this if you have triggers on the tables that you do not want to invoke during data reload. 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.

Use conditional commands (for example, add an IF EXISTS clause) to drop databases and other objects. This option is not valid unless --clean is also specified.

Dump data as INSERT commands (rather than COPY). This will make restoration very slow; it is mainly useful for making dumps that can be loaded into non-PostgreSQL-based databases. Also, since this option generates a separate command for each row, an error in reloading a row causes only that row to be lost rather than the entire table contents. Note that the restore may fail altogether if you have rearranged column order. The --column-inserts option is safe against column order changes, though even slower.

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 specified timeout. The timeout may be specified in any of the formats accepted by SET <statement_timeout>. Allowed values vary depending on the server version you are dumping from, but an integer number of milliseconds is accepted by all Greengage DB versions.

Do not dump security labels.

Do not output commands to select tablespaces. With this option, all objects will be created in whichever tablespace is the default during restore.

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.

Force quoting of all identifiers. This option is recommended when dumping a database from a server whose Greengage DB major version is different from pg_dumpall, 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.

Dump resource queue definitions.

Dump resource group definitions.

Output SQL-standard SET SESSION AUTHORIZATION commands instead of ALTER OWNER commands to determine object ownership. This makes the dump more standards compatible, but depending on the history of the objects in the dump, may not restore properly. A dump using SET SESSION AUTHORIZATION will require superuser privileges to restore correctly, whereas ALTER OWNER requires lesser privileges.

Output Greengage DB syntax in the CREATE TABLE statements. This allows the distribution policy (DISTRIBUTED BY or DISTRIBUTED RANDOMLY clauses) of a Greengage DB table to be dumped, which is useful for restoring into other Greengage DB systems.

Do not output the table distribution clauses in the CREATE TABLE statements.

Show help about pg_dumpall command line arguments, and exit.

Specifies parameters used to connect to the server, as a connection string. See Connection Strings in the PostgreSQL documentation for more information.

The host name of the machine on which the Greengage DB master is running. If not specified, reads from the PGHOST environment variable or defaults to localhost.

Specify the name of the database in which to connect to dump global objects. If not specified, the postgres database is used. If the postgres database does not exist, the template1 database is used.

The TCP port on which the Greengage DB master is listening for connections. If not specified, reads from the PGPORT environment variable or defaults to 5432.

The database role name to connect as. If not specified, reads from the PGUSER environment variable or defaults to the current system role name.

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.

Force a password prompt.

Specify a role name to be used to create the dump. This option causes pg_dumpall to issue a SET ROLE <rolename> command after connecting to the database. It is useful when the authenticated user (specified by -U) lacks privileges needed by pg_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.
