Please post the table definitions including indexes and whatnot (ie:
\d <table> output).  Also, make sure your tables are 'ANALYZE'd.
Also, the mapserver .map file might help.  If you could also turn on
statement logging in the PG backend and then take the *exact* queries
mapserver is running and run them using 'explain analyze' and posting
them here, that would be a great help.
