you'd likely be better off with npgsql, which is a native .net data
provider for postgres, instead of ODBC.

you realize 'character(n)' are fixed length fields? so if name is 'joe
blow', it will be padded to 100 characters with spaces? thats almost
never what you want to do. instead use varchar(100) or character
varying(100) (same thing), or just use text (no length specified), these
formats return just what you store ('joe blow' will return an 8 char
string).
