[ADMIN] lo_import

[Maurício Cruz]

Hi all,

I'm trying to use lo_import to import a file into my database, if I
execute from postgres runing in my local machine
it works perfectly, but if I do it in the postgres runing in the server,
it says "No such file or directory"

I Guess postgres only see file on the machine it is runing and not
through the network...
I will have to upload the file into the server and then use import ?
is there any other way ?

Thanks every one.

It's the default behavior.

The lo_import/lo_export functions read/write files in the same file system
where postgres server is running [1]...

If you need send some file from your client to your database server you
must verify the implementation of libpq API in your programming language to
use another functions (lo_creat, lo_open, lo_write, lo_read) to create LOs
from your client side of connection into your server [2].

Another way is using "psql" client program [3] to import/export large
objects.
