[postgis-users] Speed issues again

[Paul Ramsey]

If you mapserver is slow when running a query, the cause is almost 
always the lack of an index on the unique column of the database. If you 
declare a unique key in your DATA statement with "USING UNIQUE" then 
that column should have an index. If you do not, then 'oid' should have 
an index (create index thetable_idx on thetable (oid);).
