I am upgrading my 10.0 geodatabase to 10.2. All my rasters are failing because I am using st_raster storage type.
I followed instructions  to install libst_raster_pg.dll but keep getting version mismatch errors. Apparently I can only find this dll for PostgreSQL 9.0! Even on a 10.2.2 installation there's only 1 dll and that's for pgsql 9.0...
It is stated very clearly  that pgsql 9.2 is supported at arcgis 10.2.x. There are not restrictions nor limitations pointed out.
