Eduardo,

Did I never respond to this?  I prepared an email about how this relates
to a recent fix in the postgis driver.

On further consideration, there are several functionaly equivelent
ways of defining EPSG 4326 and it seems likely that you are getting
text that is slightly different, and thus ogr2ogr is creating a new
SRID.

If you capture the WKT column of the spatial_ref_sys table, and save
it to a file name srid_4326.prj and then use "-t_srs srid_4326.prj"
it should ensure the standard srid gets used.

Best regards,
