This implies incorrect option switches supplied either through the postmaster's -o command-line option, or from the client side through the "options" part of the startup packet. The -o part would affect all clients, so if you are able to connect at all (eg with psql) you can reject that theory. Unfortunately I dunno anything about VB.NET and have no idea what might make it put options in the startup packet --- there's certainly nothing suggesting it in your connection string. Are there any GUI configuration dialogs anywhere controlling database connection parameters? Another longshot is that traditionally PG clients have interpreted the PGOPTIONS environment variable as containing an option string, but it seems a bit unlikely that that would be set in a Windows context (and I don't know whether VB honors it anyway). regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
