time setting

I've set my date format to the following in postmaster.conf:

PGDATESTYLE=NonEuropean,US

THe date format is exactly how I want it but I keep getting date setting
conflict errors like this one:
NOTICE:  Conflicting settings for date

I've done SET DATESTYLE=NonEuropean,US when connected to my database as well
but I still get the error.  I noticed someone mentioned the -e argument for
postmaster but I didn't see anything about it in man postmaster.

Any help would be greatly appreciated.  The reason I switched over is that
the site currently accessing the database is running on IIS/ASP/VBScript and
<%=Date%> records the date in this format.

Thanks again,
