Re: pg_dump and errors

Here some more information:

Versions:

the pg_dump used is 7.4.2 ( under debian )
the Server im getting the DB from is 7.3.2

I did:

pg_dump -h www -U postgres db_name > 20040531-db_name.dump
psql db_name < 20040531-db_name.dump

got this alot. is this an Error ?
Query buffer reset (cleared).

On runing the psql two files created in the working directory, something like ( i was able to delete them using MC ):
?\012\301\006,B\0360(at)\006\330\000\021?@\004?\000.................
and
C?F\004

The following error accour becouse 7.3 was compiled by me under RH on a specific path, the current version use other paths.
ERROR: could not access file "/usr/local/pgsql7.3/lib/plpgsql.so": No such file or directory
ERROR: function plpgsql_call_handler() does not exist

if I use createlang before the dump i just get:
ERROR: function "plpgsql_call_handler" already exists with same argument types
ERROR: language "plpgsql" already exists

The next error is strange, the relation ( table ) exist as create in the dump file, maybe its and order issue ?
ERROR: relation "forum_tree" does not exist

The next one is realy strange. the relation forum_tree2 exists in one of the development phase, it was deleted long time ago:
ERROR: relation "forum_tree2_node_id_seq" does not exist

lots of:
invalid command \n<F0><E5><F9><E0><E9>

save as the error for forum_tree:
ERROR: relation "forum_files" does not exist

same as the error for forum_tree2_node_id_seq
ERROR: relation "forum_files2_file_id_seq" does not exist

I found a way to move it to 7.4.2 but its kinda pain.
I recreated all the scheme using my source code. then after edit the dump file by hand ( fixing the strange forum_tree2 relations ) dumping all the data into using Insert.

Am i doing something wrong ?

Hello

Im getting strange errors when restoring data from pg_dump files:

ERROR: duplicate key violates unique constraint "products_pkey"

Im using pg 7.4.1 on woody ( debian ).
this is not the first time such hapens and i have a constant fear from backup failures.

once I even had to move a db from 7.3 to 7.4 and pg_dump returned me some errors on not existing tables ( ones which i deleted before )

this is the line i use ( i started to seperate the scheme from the data becouse its easier to me to edit the files if something happens )

/usr/bin/pg_dump -s -f /var/pg_dumps/db1 db1
/usr/bin/pg_dump -a -f /var/pg_dumps/db1 db1

Any ideas how to avoid such errors ( if possible at all ) ?

Thanks
