How to...?

    Did I miss something here?  I just looked through the migration
file for 6.2.1->6.3, and it doesn't seem to say, but how do you dump
the data from a v6.2.1 database and then reload it to a v6.3 one?

    Using v6.2.1's pg_dump/pg_dumpall, I did:

pg_dumpall -o > db.dump

    That worked.

    Then, I installed v6.3, and using its psql, I did:

psql -e < db.dump

    That failed miserably.

    First thing that failed was building the new pg_user...so I cut
out that and did it manually using createuser...

    Then, using what was left, I did:

psql -e < db.dump

    Again.  Failed misearbly, with the following coming from the 'copy
to <relname> from stdin;' section:

344984  johnb   xgSldZdYEgIWo           clio.trends.ca  n       \N

 \d [<table>] -- list tables and indices, columns in <table>, or * for all
 \da          -- list aggregates
 \dd [<object>]- list comment for table, field, type, function, or

    So, is there, like, a trick to this? *raised eyebrow*  Have I
missed something important here?

Thanks...

OK.

Check what is in the file around this line.  It has existed the COPY for
some reason, and the \N is triggering the \? output.
