Hi,
If you do not need to reproject or you are reprojecting just between KKJ zones
you can live without towgs84 parameters. However, reprojecting to/from all the
other systems will give an error of 150-200 meters. That is the thing that is
not safe. Updating spatial_ref_sys is safe.

Thank's Jukka,
On my spatial_ref_sys-table, there is proj4text like:
+proj=tmerc +lat_0=0 +lon_0=27 +k=1.00 +x_0=350 +y_0=0 +ellps=intl +units=m +no_defs
So towgs84-parameter is missing.
If it is not, update the record.
It this safe? Can it affect with unwanted result somewhere?

Hi,
I suppose that towgs84 parameters are missing. You can check this with psql:
select proj4text from spatial_ref_sys where srid=2393;
The result should be close to
+proj=tmerc +lat_0=0 +lon_0=27 +k=1.00 +x_0=350 +y_0=0 +ellps=intl
+towgs84=-90.7,-106.1,-119.2,4.09,0.218,-1.05,1.37
