I dont think so Bob.
Check this out:
In this case the table still exists
create table srid_inexistent_test(
> id serial not null);
> select * from
> addgeometrycolumn('public','srid_inexistent_test','the_geom',999999,'POINT',2);
> NOTA: CREATE TABLE criará sequência implícita
> "srid_inexistent_test_id_seq" para coluna serial "srid_inexistent_test.id"
> ERRO: AddGeometryColumns() - invalid SRID
> CONTEXT: SQL statement "SELECT AddGeometryColumn('', $1 , $2 , $3 , $4 ,
> $5 , $6 )"
> função PL/pgSQL "addgeometrycolumn" linha 4 em comando SQL
> ********** Erro **********
> ERRO: AddGeometryColumns() -* invalid SRID
> *SQL state: P0001
> Contexto: SQL statement "SELECT AddGeometryColumn('', $1 , $2 , $3 , $4 ,
> $5 , $6 )"
> função PL/pgSQL "addgeometrycolumn" linha 4 em comando SQL
In this particular table I've dropped it:
drop table spatial_ref_sys;
> create table srid_inexistent_test(
> id serial not null);
> select * from
> addgeometrycolumn('public','srid_inexistent_test','the_geom',999999,'POINT',2);
> ERRO: relação "spatial_ref_sys" não existe
> LINE 1: SELECT SRID FROM spatial_ref_sys WHERE SRID = $1
> ^
> QUERY: SELECT SRID FROM spatial_ref_sys WHERE SRID = $1
> CONTEXT: PL/pgSQL function "addgeometrycolumn" line 74 at comando SQL
> comando SQL "SELECT AddGeometryColumn('', $1 , $2 , $3 , $4 , $5 , $6 )"
> PL/pgSQL function "addgeometrycolumn" line 4 at comando SQL
> ********** Erro **********
> ERRO: relação "spatial_ref_sys" não existe
> SQL state: 42P01
> Contexto: PL/pgSQL function "addgeometrycolumn" line 74 at comando SQL
> comando SQL "SELECT AddGeometryColumn('', $1 , $2 , $3 , $4 , $5 , $6 )"
> PL/pgSQL function "addgeometrycolumn" line 4 at comando SQL
PostGIS uses spatial_ref_sys table to verify, when you create a geometry
table, if the projection you're using is available.
If I've made any mistakes, experts, please correct me :D
