That doesn't make much sense. Views look like tables. Tables don't
have arguments or parameters. If you want a subset of the records
defined by a view, you can use the where clause.

Recent versions from Postgres allow set returning functions. You can use these
in the from item list. I don't use these, but my memory is that there have
been some significant improvements for version 8.0, so you might want to
look at the 8.0 beta for your initial development. 8.0 will probably be
released in a month.
