DROP TABLESPACE(7) SQL Commands DROP TABLESPACE(7)NAME
DROP TABLESPACE - remove a tablespace
SYNOPSIS
DROP TABLESPACE [ IF EXISTS ] tablespacename
DESCRIPTION
DROP TABLESPACE removes a tablespace from the system.
A tablespace can only be dropped by its owner or a superuser. The tablespace must be empty of all database objects before it can be
dropped. It is possible that objects in other databases might still reside in the tablespace even if no objects in the current database are
using the tablespace. Also, if the tablespace is listed in the temp_tablespaces setting of any active session, the DROP might fail due to
temporary files residing in the tablespace.
PARAMETERS
IF EXISTS
Do not throw an error if the tablespace does not exist. A notice is issued in this case.
tablespacename
The name of a tablespace.
NOTES
DROP TABLESPACE cannot be executed inside a transaction block.
EXAMPLES
To remove tablespace mystuff from the system:
DROP TABLESPACE mystuff;
COMPATIBILITY
DROP TABLESPACE is a PostgreSQL extension.
SEE ALSO
CREATE TABLESPACE [create_tablespace(7)], ALTER TABLESPACE [alter_tablespace(7)]

Hi,
What does this line do in bash?
MAILDROP_GROUP="@@";
Is this just assigning a string? or does it have special meaning?
Thanks in advance.
