Re: Problem with lo_export() and lo_import() from remote machine.

Hi Milen A. Radev,

Thank you for your response.

I have read this in PostgreSQL documentation.

I usually log in to postgresql server with admin username.

But whatever its, according to documentation, if client machine's user has
write access
permission, this query should successfully be executed.

Both PostgreSQL server/client are Windows XP machines.

Any suggestion???

:)
