You could use tablespaces for that bit, BUT:

I'm looking at ways to select rows with a timestamp column of "last
week" relative to the current server time.
In 8.3 there's "isoyear" so is this a good approach?
extract( isoyear from foo_time )
= extract( isoyear from now() - interval '1 week' )
AND
extract( week from foo

to or from a disk file, not a single col
Thank you very much.
I`ve also worked out how to do this simply from bash

just change whatever you are storing to be in vertical structure,
instead of horizontal. so instead of create table foo(a int, b int, c
int, etc), try:
create table foo(name varchar, val int);

Hi all,
I'm developing a new, free, XA compliant transaction manager.
One of the first resource manager I would be glad to support is PostgreSQL;
after some googling I have found no information related to PostgreSQL and XA
