Problems reading dump files coming from version 7.1 into version 8.1.

Dear all,

I have been using PostgreSQL version 7.1 for years, but recently my hard
disk had problems, I decided to change it and took the opportunity to move
to the new version 8.1. This is a sun/solaris machine, v7.1 was working
under Solaris 2.6, v8.1 is now running under Solaris 2.10.

To speed up and simplify the transfer I decided to produce dump files, the
documentation indicates to use the pg_dump of the new version to produce
them, could you give me some explanation on how this is possible (the
libraries that v8.1 uses are very different from the ones used by v7.1, so
it complains that it cannot find them), are you sure this is possible and
how?

Since I could not figure how to make the pg_dump of v8.1 work correctly. I
used the pg_dump of v7.1 and I obtained 5 files of about 5Go.

When I tried to read them back into 8.1, psql complained of errors related
to literal carriage return which should be replaced by \r

I found on the mailing list a solution that someone had used which consisted
in replacing the literal carriage returns using the “sed” program: sed
‘s/^M/\\r/’ file.dump > newfile.dump

The files were reduced to a bit more than 1Go each, but when I tried to read
them in 8.1, it failed again with the same type of error.

Therefore I have two questions, (1) is there a patch which would allow v8.1
to read v7.1 dump files ? if not how can I run pg_dump of v8.1 on the v7.1
database?

Thanks in advance,

Sincerely,

PS:In fact, I am wondering if I need to move to 8.1, may be I could stick to
7.3 which apparently would read the 7.1 dump files.
