multiple join with a postgrsql table

[cjesch@…]

multiple join with a table that is part of a postgresql database doesn't work.
Looking at the source code shows that it hasn't been implemented (only dbf and 
mySQL)

Added PostgreSQL support.

Mark can you include here an example JOIN object from your test mapfile, joining
a postgresql table?  (I will update the mapfile reference with an example and
notes http://mapserver.gis.umn.edu/docs/reference/mapfile/join)

thanks.
