Problem doing pg_dumpall

Hi,

As usual I wrote this email because I'm getting problems with posgtresql,
this time is with the pg_dumpall command, here´s the story:

We always make a copy of our database running

root(at)realserver#/var/lib/pgsql/bin/pg_dumpall > backup

It always worked fine but lately when I run this command It stops in the
middle of the process... because of the size of the backup file 2.5Gb
against 6Gb when doing it normally.

I looked at the tail of the backup file (#tail -100 backup | less)

And all I see is:

The first two tables are part of our database the rest as I understand
are part of the database template1 which must exist in order to create
other datbases when need it.

I've checked at the running database using pgAdmin III and everything
apperars normal there are three DB mydatabase, template0 and template1,
the user postgres also exists and has proper rights.

Does anyone know what the problem is...? any ideas...?

PLAN B

By now I run /var/lib/pgsql/bin/pg_dump -d mydatabase > backup to make
backup copies, but when I recover that copy in other machine the
constrains and indexes dissaper, I follow this steps:

root(at)anothermachine#su postgres
$createdb mydatabase
$psql -d dbsa < backup

Do you think that I have to recover the schema and then all the data...?

I know that maybe this not a big deal because in the worst case I can
create the Indexes and constraints manually, but I really want to know why
is that? Am I donig things wrong..?

I hope you can help me...

Thanks for taking some of your time to look at this message.

Bye
