Remove embedded Python interpreter support (libpython) from perf, as
all Python scripts have been migrated to standalone scripts using the
perf Python extension module.
Changes include:
- Remove libpython detection and build flags from Makefile.config.
- Remove legacy Python script installation rules from Makefile.perf.
- Delete tools/perf/util/scripting-engines/trace-event-python.c and
tools/perf/scripts/python/Perf-Trace-Util/Context.c.
- Remove Python scripting engine registration from
trace-event-scripting.c.
- Remove libpython from the supported features list in builtin-check.c
and Documentation/perf-check.txt.
- Delete the legacy Python scripts and bin wrappers in
tools/perf/scripts/python/ and update shell tests.

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My notes (which may be out-of-date) on setting up postgresql so you can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