Tablespace with multiple locations

Description:

Hello,

I m kindly requesting a clarification regarding a debatable subject in one
of my projects, that if it's possible to create one global tablespace and
assign many locations like the following example:

create tablespace TBS1 location ('/pgdata1','/pgdata2');

Which will be helpful on database migration, once the new database to be
restored needs further available space than the created tablespace ( if the
new DB is larger than the existing tablespace ), so it can be automatically
distributed on the assigned locations ( filesystems ) with no need for
manual intervention to distribute the schema objects between many
tablespaces that can't be done automatically.

And if a tablespace needs to be extended on a physical partitioned disk
device that is not configured as a logical volume.

Thank you,
Hussein Younes
