Small nitpicks. All column-related ALTER TABLE commands take an exclusive table lock in PostgreSQL. The difference is that adding a column without default doesn't cause a table rewrite, so the lock is held only for a short time. The time taken is more accurately proportional to table size, not row count.
The documentation in this tree is in plain text files and can be viewed using any text file viewer. It uses ReST (reStructuredText) [1], and the Sphinx documentation system [2]. This allows it to be built into other forms for easier viewing and browsing. To create an HTML version of the docs: * Install Sphinx (using ``sudo pip install Sphinx`` or some other method) * In this docs/ directory, type ``make html`` (or ``make.bat html`` on Windows) at a shell prompt. The documentation in _build/html/index.html can then be viewed in a web browser. [1] http://docutils.sourceforge.net/rst.html [2] http://sphinx-doc.org/
