How to Output PSQL Errors to a Log File?

Hi,

I used 'pg_dumpall' to dump the database in Postgres 7.1.3 and I'm in the process of restoring the databases in Postgres 8.3.8. There were lots errors showed on the screen when I ran this command 'psql -e template1 -f 21.bak' and it actually displayed the line numbers where the errors occurred. Because there were so many errors, and I wanted the errors to be logged to a log file so I ran this command 'psql -e template1 -f 21.bak > late22error.txt', but late22error.txt didn't log the errors, it just logged the transactions. What option should I use to tell psql to log all errors to a log file?

I'm running on RHEL 3.9.

Thanks
Mary

Wow that takes us back aways. Did you dump the 7.1 with the 8.3 version of
pg_dump? That should help.

Thanks

you need to redirect stderr, see

variety of options

psql <...your options...> 2> errorfile.txt

This is the general shell error redirection. This will work if psql
outputs errors to stderr and not stdout. (Try it out ;))

Re: How to Output PSQL Errors to a Log File?

No. I dumped the 7.1 with the 7.1 version of pg_dump.
Is it better to dump with the 8.3 version of pg_dump? I thought I read it some where in the mailing lists. I don't know how I would be able to dump with the 8.3 version of pg_dump. The database and Postgres 7.1 is loaded on the current production box and Postgres 8.3.8 is loaded on a dev server that I plan to migrate the database to.

Please advise.
Mary

Since you will be restoring your data to a 8.3 server, you should use
8.3 pg_dump, yes.

I thought I read it some where in the mailing lists. I don't know
how I would be able to dump with the 8.3 version of pg_dump. The
database and Postgres 7.1 is loaded on the current production box and
Postgres 8.3.8 is loaded on a dev server that I plan to migrate the
database to.

After setting tcpip_socket to true and granting access using
pg_hba.conf, you can connect from 8.3 machine to 7.1 machine (you may
need to change your firewall settings, etc), like:

pg_dump -h ip/hostname/of/7.1/machine dbname -f dump.file

You don't need to compile and install 8.3 to 7.1 machine.

Cool! That worked. Thanks. Now I just have to see if I can migrate the database data from 7.1 to 8.3 successfully.
