Bug reference: 15867
Logged by: Ed Sabol
Email address: edwardjsabol@gmail.com
PostgreSQL version: 10.9
Operating system: RHEL/CentOS 6.9
Description:
The psql documentation at
https://www.postgresql.org/docs/current/app-psql.html says this should work,
but it does not.
Steps to reproduce:
1. Create a table named "sometable" in some convenient user database:
create table sometable (a1 varchar(100));
2. Execute psql and connect to that database.
3. Issue the following command:
\copy sometable from program '/bin/echo'
The following error message is returned:
program: No such file or directory
If you instead use the server-side COPY command, it works, of course:
copy sometable from program '/bin/echo';
select * from sometable;
Please fix psql \copy to work as documented. There are many use-cases for
running the program on the client-side (file permissions, the existence of
the program, etc.).
