Обсуждение: multiple hard disk

Is there any way (excluding RAID) to split a database information
between multiple hard disks?
Thanks in advance

I think you can selectively move table/index files to another location and
create symbolic links from the original location.  The postmaster must be
stopped while you are doing this.

Keep in mind that Postgres will create separate files for each 1GB of a
table.  So if your table grows substantually after you set this up, new
segment files may have been created, thus partially undoing the effect you
were trying to achieve.

How can one tell the location of a table/index?
In my "data/base" directory all I see is directories with numerical names.
Inside of of those directories there are files, also with numerical names.
The only two files which are not numbers are PG_VERSION and
pg_internatl.init.
