<br>
Would it be possible to extend functions as st_transform with a
version, where the second parameter is not an EPSG-number but a
full PROJ-string? I work a lot with old maps for which I know te
projection parameters, but these are not available in the official
EPSG database. With mapserver and the gdal utilities I can specify
the complete PROJ4-string, but with PostGIS I have to extend the
geometry_columns table and use a user defined EPSG-number. That is
troublesome when there are many projections, but worse, I cannot
share them with other databases without adapting their
geometry_colums tables too.<br>
<br>
I guess this would need quite a lot of adaptations within the
POSTGIS code, although they would technically not be very
difficult. The project would be fundable, but do you think it can
and should be done for PostGIS?<br>
