Proj4text is still working

[José Carlos Martínez]

Hi list

I am making some changes in proj4text of the spatial_ref_sys table, to 
apply a transformation between datums (+towgs84).

It appears that PostGIS is not using the values from proj4text, and 
instead is using the values from proj.db in the proj directory.

I would like to ask if proj4text values still take priority (as in 
previous versions), with respect to proj.db?

I mean, the first place PostGIS looks at the values to perform a 
coordinate transformation is still proj4text?

Thanks

Jose Martinez
