First of all, let me apologize if this question has been answered in a FAQ.

I have a problem with upgrading postgresql 6.1 to 6.3.2. Compilation and
installation of the database system is no problem, the trouble start when I
try to move the contents of the old database to the new one.

This is the procedure I followed.

0. Platform is:
   SunOS epidemix 5.5 Generic_103093-06 sun4m sparc SUNW,SPARCstation-4
1. compile version 6.3.2
2. run 6.3.2 version of pg_dumpall to dump the contents of the old database.
   The old poster is still running

   This will lead to a number of warnings/errors about the pg_shadow table, i.e.
that it does not exist. From the documentation , I understand that this is
correct since 6.1 doesn't have this table.

   When I check the captured output of pg_dumpall, none of my users has been
saved to the output. Needless to say, I also dumped the database with the old
version of pg_dumpall. During the dump process, no errors or warnings occur.

3. kill the postmaster. Renamed postgres directory to postgres.old, created new
postgres directory. Went back to source and did gnu-make install, followed by
initdb. No problems occured.

4. When I try to reload my old data from the dump that has been made with the
6.3.2 version of pg_dumpall, no users are created and the restore process stops.
If I create the users manually and then remove the first few lines from db.out
that are responsible for deleting the body of pg_shadow, the restore process
stops with an error that mentions a buffer overflow

When I try to reload my old data from the dump that has been made with the 6.1
version of pg_dumpall, my users are created, but I get an error that the users
are not listed in pg_shadow and the restore process stops.

From the documentation, I understood that pg_user now is a view of pg_shadow,
how is it possible then that when I update pg_user, the changes are not made to
pg_shadow?

Anyhow, I've been trying for a day and a half to restore my database and nothing
works. Since it is a more-or-less production database, I restored the 6.1 copy
so that we could continue our work.

What is wrong? And more importantly, how do I fix it?!

Thanks in advance for your reactions!
