    Subject[PATCH 21/25] perf script: Add Python script to export to postgresql
    Date
    From: Adrian Hunter <adrian.hunter@intel.com>

    Add a Python script to export to a postgresql database.

    The script requires the Python pyside module and the Qt PostgreSQL
    driver. The packages needed are probably named "python-pyside" and
    "libqt4-sql-psql"

    The caller of the script must be able to create postgresql databases.

    The script takes the database name as a parameter. The database and
    database tables are created. Data is written to flat files which are
    then imported using SQL COPY FROM.

    Example:

    $ perf record ls
    ...
    $ perf script report export-to-postgresql lsdb

    My notes (which may be out-of-date) on setting up postgresql so you can
    create databases:

    fedora:

    $ sudo yum install postgresql postgresql-server python-pyside qt-postgresql
    $ sudo su - postgres -c initdb
    $ sudo service postgresql start
    $ sudo su - postgres
    $ createuser -s <your username>

    I used the the unix user name in createuser.

    If it fails, try createuser without -s and answer the following question
    to allow your user to create tables:

    Shall the new role be a superuser? (y/n) y

    ubuntu:

    $ sudo apt-get install postgresql
    $ sudo su - postgres
    $ createuser <your username>
    Shall the new role be a superuser? (y/n) y

    You may want to disable automatic startup. One way is to edit
    /etc/postgresql/9.3/main/start.conf. Another is to disable the init
    script e.g. sudo update-rc.d postgresql disable
