[gdal-dev] VRT OGRVRTDataSource filter & python function

This yields the correct behavior. However, looking at logs with
CPL_DEBUG=ON and enabling postgis logs makes me think it might still be
filtered client side (in Mapserver).

have a Python WSGI server that intercepts requests and generate mapfiles on
the fly, and use Python MapScript to get the result.

This is an interesting idea! I have never used MapScript and didn't realize
until today that it provides bindings to intercept Mapserver methods in
this manner.  Ultimately for my application I'm trying to do some work
on-the-fly with data in cloud storage which is in not quite the
right format.  Yet another option I am considering is to do some batch
processing to convert my "not quite right" data into a vector tile cache.

Thanks for the ideas!
