I was thinking about asking the same question, because PGSQL appears to
have two things called 'schema'.  The pg_dump (ver 7.4.3) man page says:
         -n (--schema) appears to say 'namespace' and 'schema' are
synonymous - "Dump contents of 'schema'".
         -s option appears to say 'data definition' and 'schema' are
synonymous - "dump only the schema (data definitions), no data".

So, in summary, a schema (namespace) contains a schema (data definitions)?
