It seems that I /was/ a bit to optimistic, indeed.

Here's the problem I'm having now, and I didn't know this was a problem 
until I heard it from the client.  The problem is that I can *update* 
records just fine after setting the Max LongVarChar above 8190, but I 
cannot *add* new records.  I get this error instead:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'
can't alloc Desc Handle yet
/cora/coraModules/news/newsUpdate.asp, line 1054

When I set the value back to 8190, I can add new records and update 
records just fine (as long as I don't go over that value).

Here's the code I'm using to add new records (keep in mind that this is 
ASP using ADO to update the database--do not me to switch it to a SQL 
statement, it still will not work, as I have already tried):

Set DBConn = Server.CreateObject("ADODB.Connection")
DBConn.Open "DSN=DatasourceName;UID=username;PWD=password;"

Set NewsRS = Server.CreateObject("ADODB.Recordset")
NewsRS.CursorLocation = adUseServer
NewsRS.CursorType = adOpenKeyset
NewsRS.LockType = adLockOptimistic
NewsRS.Open "tblNews", DBConn, , , adCmdTable

NewsRS("DateAdd") = Now
NewsRS("Keywords") = Keywords
NewsRS("DateModified") = Now
If (StrComp(ArtType,"1") = 0) Then
     NewsRS("News") = 1
     NewsRS("News") = 0
End If
If (StrComp(ArtType,"2") = 0) Then
     NewsRS("Topic") = 1
     NewsRS("Topic") = 0
End If
If (StrComp(ArtType,"3") = 0) Then
     NewsRS("Review") = 1
     NewsRS("Review") = 0
End If
NewsRS("ReleaseDate") = ValidDate
NewsRS("Title") = ArtTitle
If ArtPDF Then
     NewsRS("PDFLink") = 1
     NewsRS("PDFLink") = 0
End If
NewsRS("PDFURL") = ArtPDFFile
If (StrComp(ArtCopyType, "HTML", vbTextCompare) = 0) Then
     NewsRS("FormatHTML") = 1
     NewsRS("FormatHTML") = 0
End If
If (StrComp(ArtCopyType, "Text", vbTextCompare) = 0) Then
     NewsRS("FormatText") = 1
     NewsRS("FormatText") = 0
End If
If ArtPressRelease Then
     NewsRS("PressRelease") = 1
     NewsRS("PressRelease") = 0
End If
If ArtCalendar Then
     NewsRS("Calendar") = 1
     NewsRS("Calendar") = 0
End If
If ArtHome Then
     NewsRS("HomePage") = 1
     NewsRS("HomePage") = 0
End If
If ArtRevised Then
     NewsRS("Revised") = 1
     NewsRS("RevisedOn") = ValidRevisedDate
     NewsRS("Revised") = 0
End If
NewsRS("ArticleCopy") = ArtCopy


Set NewsRS = Nothing
Set DBConn = Nothing

Line 1054 is NewsRS.Update.  ArticleCopy is the "text" column in the 

Here is the SQL code I've dumped from PostgreSQL for "tblnews":

CREATE TABLE tblnews (
     id serial NOT NULL,
     keywords character varying(255),
     dateadd timestamp without time zone,
     datemodified timestamp without time zone,
     news boolean DEFAULT 'f',
     topic boolean DEFAULT 'f',
     review boolean DEFAULT 'f',
     releasedate timestamp without time zone,
     revised boolean DEFAULT 'f',
     revisedon timestamp without time zone,
     title character varying(255),
     pdflink boolean DEFAULT 'f',
     pdfurl character varying(255),
     pressrelease boolean DEFAULT 'f',
     calendar boolean DEFAULT 'f',
     homepage boolean DEFAULT 'f',
     enteredby character varying(50),
     formattext boolean DEFAULT 'f',
     formathtml boolean DEFAULT 'f',
     articlecopy text

Here are the settings I have for my DSN (ODBC settings):

CommLog (unchecked)
Parse Statements (unchecked)

Int 8 As = default
Protocol = 7.X,6.4+
OID Options: Show Column (unchecked)
OID Options: Fake Index (grayed out; unchecked and unable to check)
Connect settings (empty)

The client is very antsy about this and wants it fixed ASAP.  Any ideas?
