Обсуждение: Fwd: Bug#308535: postgresql-client: [psql] manual page does not document ~/.pgpass file

Hi PostgreSQL developers!

We recently got the bug report below. Do you agree that documenting
~/.pgpass in psql(1) is a good idea?

Thanks for considering and have a nice day!

Martin

Package: postgresql-client
Version: 7.4.7-6
Severity: minor

psql(1) manual page does not mention in the FILES section ~/.pgpass file
and how it is used. It should include:=20

  FILES

      ...

      o The file ~/.pgpass in is a file that can contain passwords to be
    used if the connection requires a password (and no password has
    been specified otherwise). This file should have lines of the
    following format:

          hostname:port:database:username:password

    Each of the first four fields may be a literal value, or *, which
    matches anything. The password field from the first line that matches
    the current connection parameters will be used. (Therefore, put
    more-specific entries first when you are using wildcards.) If an entry
    needs to contain : or \, escape this character with \.

    The permissions on .pgpass must disallow any access to world or group;
    achieve this by the command chmod 0600 ~/.pgpass. If the permissions
    are less strict than this, the file will be ignored.

This explanation was exerpted from=20
http://www.postgresql.org/docs/7.4/static/libpq-pgpass.html
I have no idea why it is there, where nobidy is looking

On that theory we'd have to replicate large parts of the libpq
documentation on every one of the "client application" pages,
which doesn't seem very maintainable.  (.pgpass is just the tip
of the iceberg; the "environment variables" and "SSL support"
pages are also pretty critical for users to know about.)

I agree that there needs to be some more prominent mention,
but this doesn't look like the way to do it.  Maybe some
"see also" links?

Have you looked at the current docs?  8.0.3 has this in the second
paragraph of the psql Usage section:

    http://www.postgresql.org/docs/8.0/static/app-psql.html

    It is also convenient to have a ~/.pgpass file to avoid regularly having
    to type in passwords. See Section 27.12 for more information.

This was added in February:

    revision 1.133
    date: 2005/02/11 04:19:05;  author: momjian;  state: Exp;  lines: +22 -15
    Mention that some psql environment variables come from libpq and note
    more variables can be found in the libpq manual section.

    Mention .pgpass in the psql manual page section dealing with connection
    parameters and point to the libpq section for more details.

Is that sufficient?

Maybe it would be a good idea to have a manual page called somelint like
libpq-connect and document it there.  The other man pages could then
reference it.

A prominent pointer (URL and hint to local documentation) would
certainly be adequate then.

Thanks and have a nice weekend!
