You can't delete from a full disk :)No, really: database systems need space for logging, WAL, whatever.And even with delete PostgreSQL will free no single byte, as deleting is done with marking the row as deleted. Read up on multi version concurrency why this has to be that way.
To reclaim space:

I am new to postgres sql and have a problem with an
sql statement which I hope you can help me with.
I want to do some calculation on the result of a

Hi All,
the following takes about 2 seconds to run:
select route,not_in_route2(route) from ksanrt
limit 5,
but if i limit it to anything greater than 5 it takes forever to come
back. Forever as in I always cancel the query.
Any reasons why?

Those are very interesting ideas. Thanks. I've been playing around with
pg_dump. Modifying it to selectively dump/restore tables and columns is
pretty easy. But as you say, changing the data content within the data

I'm trying to test the 8.1 backport of the 8.2 GIN index and tsearch2
functionality.
The patch is applied successfully (to 8.1.4, on OS X 10.4.7 w/ xcode
2.3), the build and install goes well, stop start of postmaster is
done, but initializing tsearch2 fails:

Hello, pgsql-general.
Is it possible to create not only executable version of pg_dump and
pg_restore, but also libraries (.so, .dll) so developers can use them

I suppose it would be very usefull. For me it's for sure.
