The OGR/PostGIS gateway is actively maintained, and I have made a number 
of tweaks to it
in recent months.  I know that Tyler Michell and I have both 
successfully used in it projects, but
I would have to say the OGR PostGIS support is only lightly used currently.

Please feel free to file bug reports (in the GDAL/OGR bugzilla) if you 
find any problems with the
PostGIS support in OGR.
