Hello, I think you use wrong srid : for lambert93 you should use 2154 and for lambert 2 carto it is 27582.
Anyway, if you want to use the SRID 320002120 and 310024140, your problem is related to the geometry_column view and constraints checking on geometry columns. You will have to use AddGeometryColumm with use_typmod option set to false. http://postgis.refractions.net/docs/AddGeometryColumn.html said : "Changed: 2.0.0 If you require the old behavior of constraints use the default use_typmod, but set it to false."

First of all, my PostGIS version is 2.0.1 : POSTGIS="2.0.1 r9979" GEOS="3.3.5-CAPI-1.7.5" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.9.1, released 2012/05/15" LIBXML="2.7.6" LIBJSON="UNKNOWN" TOPOLOGY RASTER Here are the steps to reproduce the problem: 1/ Create a table containing points CREATE TABLE pts ( code INT, xl2 INT, yl2 INT, geom GEOMETRY, CONSTRAINT pts_pkey PRIMARY KEY (code) ) WITHOUT oids; INSERT INTO pts (code, xl2, yl2) VALUES (1, 556866, 1902345) , (2, 689174, 2448195) , (3, 729095, 2528577) , (4, 335755, 2059702) , (5, 623207, 2210468) , (6, 850337, 1871486) , (7, 915275, 1889534) , (8, 639551, 1778327) , (9, 584365, 2273523) , (10, 649599, 2228833); 2/ Import the custom records of spatial_sys_ref specified by the French IGN. The file is provided here: http://lambert93.ign.fr/fileadmin/files/IGNF-spatial_ref_sys.sql 3/ Populate the geom column: UPDATE pts SET geom = ST_SetSRID(ST_MakePoint(xl2, yl2), 320002120); I get the following notices: NOTICE: SRID value 320002120 > SRID_MAXIMUM converted to 999442 SELECT DISTINCT ST_SRID(geom) FROM pts; Gives: 999442 But SELECT * FROM geometry_columns; Gives: 0 4/ Update geometry SRID: SELECT UpdateGeometrySRID('pts', 'geom', 320002120); SELECT * FROM geometry_columns; Gives: 999442 5/ Try the transformation from 320002120 SRID (Lambert II) to 310024140 SRID (Lambert 93): SELECT code, ST_Transform(geom, 310024140) FROM pts; I get the following error message: Invalid reserved SRID (999442). With PostGIS 1.5.3, this worked perfectly, without any error message and gave the good coordinate transformation. What should I change with PostGIS 2.0.1 in order to get the same result again? Thanks in advance for your help.
