Does Postgresql have a similar pseudo-column "ROWNUM" as Oracle?

Hi:

Oracle has a pseudo-column "ROWNUM" to return the sequence number in which a row was returned when selected from a
table.The first row ROWNUM is 1, the second is 2, and so on. 

Does Postgresql have a similar pseudo-column "ROWNUM" as Oracle? If so, we can write the following query:

select *
from (select RowNum, pg_catalog.pg_proc.*        from pg_catalog.pg_proc) inline_view
where RowNum between 100 and 200;


Thanks,
Dennis
