The algorithm has been ported to C++, so yes the python version has been
removed.
https://github.com/qgis/QGIS/blob/master/src/analysis/processing/qgsalgorithmexecutepostgisquery.cpp
Even calling it from Python will work using the old previous Python
processing provider because the compatibility is maintained.

Code in plugins (such as Processing or DB Manager) is not considered stable.
You should use the public API, when it's starting with "from qgis." core,
gui, analysis, processing etc
You should use the new database API.
