refactor session_key (__errorurl) to handle cases where the form is generated throuhg an ajax call: in case of an entity form, return the entity's absolute url. Also allow to force session key value
"""Migration test script
* migration will be played into a chroot of the local machine
* the database server used can be configured
* test tested instance may be on another host
We are using postgres'.pgpass file. Here is a copy of postgres documentation
about that:
The file .pgpass in a user's home directory or the file referenced by
PGPASSFILE can contain passwords to be used if the connection requires
a password (and no password has been specified otherwise).
This file should contain 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 \. A hostname of
localhost matches both host (TCP) and local (Unix domain socket)
connections coming from the local machine.
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.
