This will get it into your database:

insert into spatial_ref_sys
(srid,auth_name,auth_srid,srtext,proj4text) values
(3310,'EPSG',3310,'PROJCS["Custom",GEOGCS["NAD83",DATUM["North_American_Datum_1983",SPHEROID["GRS
1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["degree",0.0174532925199433]],PROJECTION["Albers"],PARAMETER["False_Easting",0],PARAMETER["False_Northing",-4000000],PARAMETER["Central_Meridian",-120],PARAMETER["Standard_Parallel_1",34],PARAMETER["Standard_Parallel_2",40.5],UNIT["Meter",1]]','+proj=aea
+lat_1=34.00 +lat_2=40.50 +lat_0=0.00 +lon_0=-120.00 +x_0=0.000
+y_0=-4000000.000 +ellps=GRS80 +units=m +datum=NAD83');

You can get the srtext for this and the nad27 projection from the
projections file at ftp://casil.ucdavis.edu
