+# To use this script you will need to have installed package python-pyside which
+# provides LGPL-licensed Python bindings for Qt. You will also need the package
+# libqt4-sql-psql for Qt postgresql support.
+#
+# The script assumes postgresql is running on the local machine and that the
+# user has postgresql permissions to create databases. Examples of installing
+# postgresql and adding such a user are:
+#
+# fedora:
+#
+# $ sudo yum install postgresql postgresql-server qt-postgresql
+# $ sudo su - postgres -c initdb
+# $ sudo service postgresql start
+# $ sudo su - postgres
+# $ createuser -s <your user id here> # Older versions may not support -s, in which case answer the prompt below:
+# Shall the new role be a superuser? (y/n) y
+# $ sudo yum install python-pyside
+#
+# Alternately, to use Python3 and/or pyside 2, one of the following:
+# $ sudo yum install python3-pyside
+# $ pip install --user PySide2
+# $ pip3 install --user PySide2
+#
+# ubuntu:
+#
+# $ sudo apt-get install postgresql
+# $ sudo su - postgres
+# $ createuser -s <your user id here>
+# $ sudo apt-get install python-pyside.qtsql libqt4-sql-psql
+#
+# Alternately, to use Python3 and/or pyside 2, one of the following:
+#
+# $ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql
+# $ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql
+# $ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql
+#
+# An example of using this script with Intel PT:
+#
+# $ perf record -e intel_pt//u ls
+# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

+# To browse the database, psql can be used e.g.
+#
+# $ psql pt_example
+# pt_example=# select * from samples_view where id < 100;
+# pt_example=# \d+
+# pt_example=# \d+ samples_view
+# pt_example=# \q
+#
+# An example of using the database is provided by the script
+# exported-sql-viewer.py. Refer to that script for details.
+#
+# Tables:
+#
+# The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
+#
+# samples
+#
+# 'samples' is the main table. It represents what instruction was executing at a point in time
+# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'.
+#
+# calls
+#
+# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
+# 'calls' is only created when the 'calls' option to this script is specified.
+#
+# call_paths
+#
+# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'.
+# 'calls_paths' is only created when the 'calls' option to this script is specified.
+#
+# branch_types
+#
+# 'branch_types' provides descriptions for each type of branch.
+#
+# comm_threads
+#
+# 'comm_threads' shows how 'comms' relates to 'threads'.
+#
+# comms
+#
+# 'comms' contains a record for each 'comm' - the name given to the executable that is running.
+#
+# dsos
+#
+# 'dsos' contains a record for each executable file or library.
+#
+# machines
+#
+# 'machines' can be used to distinguish virtual machines if virtualization is supported.
+#
+# selected_events
+#
+# 'selected_events' contains a record for each kind of event that has been sampled.
+#
+# symbols
+#
+# 'symbols' contains a record for each symbol. Only symbols that have samples are present.
+#
+# threads
+#
+# 'threads' contains a record for each thread.
+#
+# Views:
+#
+# Most of the tables have views for more friendly display. The views are:
+#
+# calls_view
+# call_paths_view
+# comm_threads_view
+# dsos_view
+# machines_view
+# samples_view
+# symbols_view
+# threads_view
+#
+# More examples of browsing the database with psql:
+# Note that some of the examples are not the most optimal SQL query.
+# Note that call information is only available if the script's 'calls' option has been used.
+#
+# Top 10 function calls (not aggregated by symbol):
+#
+# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
+#
+# Top 10 function calls (aggregated by symbol):
+#
+# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
+# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
+# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
+#
+# Note that the branch count gives a rough estimation of cpu usage, so functions
+# that took a long time but have a relatively low branch count must have spent time
+# waiting.
+#
+# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
+#
+# SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
+#
+# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
+#
+# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
+#
+# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
+#
+# SELECT * FROM calls_view WHERE parent_call_path_id = 254;
+#
+# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
+#
+# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
+#
+# Show transactions:
+#
+# SELECT * FROM samples_view WHERE event = 'transactions';
+#
+# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
+# Transaction aborts have branch_type_name 'transaction abort'
+#
+# Show transaction aborts:
+#
+# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
+#
+# To print a call stack requires walking the call_paths table. For example this python script:
+# #!/usr/bin/python2
+#
+# import sys
+# from PySide.QtSql import *
+#
+# if __name__ == '__main__':
