pgclone.copy

copy(
    dump_key: str,
    *,
    database: Union[str, None] = None,
    config: Union[str, None] = None
) -> str

Copies a database using CREATE DATABASE <dump_key> TEMPLATE <database>.

Note that we use dump keys with the same syntax that dump and restore commands take. Since copy only works with local database copies, this means the dump keys are always the database name prefixed with :.

Parameters:

Name	Type	Description	Default
dump_key	str	A name to use for the copy. Must be prefixed with : and only consist of valid database name characters.	required
database	Union[str, None]	The database to copy.	None
config	Union[str, None]	The configuration name from settings.PGCLONE_CONFIGS.	None

Returns:

Type	Description
str	The dump key that was copied.
