Just my 2 cents to complete Paul's email:
According to OpenGIS specifications, yes, SRID is an arbitrary number
given by the database for each installation.
Generic queries should not rely on a specific value of the SRID column,
but rather on another well-known value, like EPSG number (auth_srid
column)
