Regression in 1a28dc3887e8d66d5e3ff08cf7fb0a6212b873e5. The usage of CONCAT to allow SearchVector to deal with non-text fields made the generated expression non-IMMUTABLE which prevents a functional index to be created for it. Using a combination of COALESCE and ::text makes sure the expression preserves its immutability. Refs #29582. Thanks Andrew Brown for the report, Nick Pope for the review.
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 ``python -m 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/
