Обсуждение: RE: ???solution??? --> can't run pg_dump in sh script usi ng crontab

   Thank you for your help.

   I managed to get an output by mail:

"/opt/postgresql/bin/pg_dump: error in loading shared libraries:
libpq.so.2.1: cannot open shared object file: No such file or directory"

   I've just found a solution from old postgresql archive:
"You can just put the postgresql lib directory in /etc/ld.so.conf and run
ldconfig."
   It seems to be working. I've just got a dump file.
   But I have a question: is this solution enough for successful pg_dump
or I have to do something else to exclude failure ?

   Thanks
   Slava

Ist your crontab a systemwide one? (ie: /etc/crontab ?) this one's normally
run as root, but you may specify a special user. does your script run as
root, too? So you might ewant to un your script as
* * * * * su - oracle -c '/path/to/script/yourscript'

ah, that explains much.

Yes, that's it

Maybe, as I stated before, you might needt to allow root to access the
databases or to run your pg_dump-script as
   su - oracle -c 'pg_dump <dbname>'

If your database user (oracle) has PG_LIB (I don't remember the variable
exactly, but it's something like that, take a look at the INSTALL file in
the postgresql-source tree) set, then you don't even need ldconfig.

Hi !

I did a pgdump on a database. It was ok

After, all tables have dissapeard ,even those in other databases !

when I check in the data directories, all datas are here, but in pg_class,
there is no more tables ! (except system tables !)

Is there a way to retrieve my lost tables ?????

It s strange :

I can do a "SELECT.." on my tables : return 0 rows (but there is 1000 rows !!!)
but when i do "\d", it says "couldn't find any tables"...

any idea ???
