another section if required by the platform (instead of the old way of building them in section "l" and always transforming them to the platform-specific section). This speeds up the installation on common platforms, and it avoids some funny business with the man page tools and build process.

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 <xref
|
|
linkend="guc-temp-tablespaces"> setting of any active session, the
|
|
<command>DROP</> might fail due to temporary files residing in the
|
|
tablespace.
