Hi Mark,
Can you please provide the backend log? You're likely to find it under 
<postgresql installation directory>\data\pg_log if you're using the 
Windows installer defaults.

 From the sound of it, this is not an error in your code. It's not 
unlikely that you're bitten by one of the bugs in 1.2 that has been 
fixed in the coming 1.3 version. Perhaps you could try the latest 
snapshot? You'll find the latest windows binaries at:

Regards,
Thomas Hallgren
