Ooh. I like that. It would be absolutely brilliant if I could figure out how
to get it to work with ADO and the Windoze ODBC driver. I've tried appending
statement_timeout to my connection string i.e.
ConnString = "DRIVER={PostgreSQL
Unicode};SERVER=MYSERVER;DATABASE=MYDB;UID=client;set_timeout=1"
but it has no effect on a SELECT statement that takes at least 3 or 4
seconds to execute and only returns 184 (out of 600,000) records.

I've also tried different syntaxes to pass the parameter
set_timeout=1
set_timeout='1'
set_timeout=(1)
set_timeout=('1')
