The following bug has been logged on the website:
Bug reference: 13727
Logged by: Collin Stedman
Email address: zkronion@gmail.com
PostgreSQL version: 9.4.4
Operating system: Mac OSX 10.10.3
Description:
The following command works just fine:
pg_dump "postgres://my-user:my-password@my.hostname.com:5432/my-db" -Fd -f
my-dump
However, if I try to parallelize the dump...
pg_dump "postgres://my-user:my-password@my.hostname.com:5432/my-db" -Fd
--jobs=9 -f my-dump
I get the following error:
pg_dump: [parallel archiver] connection to database "my-db" failed:
fe_sendauth: no password supplied
I believe I have a patch for the bug, which I'll submit to pgsql-hackers in
response to this bug report.
