Re: pg_ [dump & restore] invalid archive problem - Mailing list pgsql-novice

Hello Roy et al...

Just following on the pg_restore thing, I tried it with the --format=t
option, and this time the error is:

pg_restore: [archiver] unsupported version (1.7) in file header.  I had
also attemped the dump with the -i option to ignore version (?), but the
result is still the same.

Googling around doesn't give me much to work on.

Using the redirection as you describe, it seems to interpret the binary
contents of the tables as text commands and hence scrolls off for some time
with "invalid command", leaving a file with a name of >100 gibberish
characters on the filesystem.  I think this may work for dumps containing
text-only tables?

/j-p.

HI j-p,

From what I can remember, (anybody feel free to correct me on this if I'm
wrong), pg_restore expects a different format to that output from pg_dump,
Not very logical I know but I was doing a similar thing a while back but it
was a few versions back now.  I was confused by the fact pg_restore did not
restore a pg_dump.  I am pretty sure that the psql < databasedump is the
way
to do it.

Did you make sure that the database you were trying to recreate was a brand
new one and owned by the same user as the original?

Maybe you could post a few error lines from the psql < databasedump command
that you ran and I'll see if I recognize anything there.

Roy

Thanks Roy...

Unfortunately that parsed the file and output lot's of invalid command
strings with nothing written to the db in the end.
What's the pg_restore command used for then, if not to restore from a
pg_dump, I wonder?

/j-p.
