Looking deeper it seems all my problems are really boiling down to one
problem: the where clause used to update the edited record back to the
server. Both access and vb generate a where clause that includes every
field in the table instead of the p-key. For various sundry reasons
such as improper handling of null values, etc. this where clause gets
busted. This problem is aggravated by the fact that all my domains get
treated as text types, although this is correctable by using a view
which I was planning to use anyways (aside: I make heavy use of
domains). This busted where clause trips up vb and access in different
ways. This may be a case where I may want to explore hacking the odbc
driver to get it to do what I want, depending on who is building the
clause. My guess is the ado driver is building it so I'm basically
hosed. It's really queer to me that they use the p-key to pull the data
out and the entire record to write the data back...what's the point of
the p-key anyways?

The odbc driver is supposed to have a property exposed to the ado
wrapper that allows you to constrain the write-back where clause to
different things, but apparently this does not work in pgsql-odbc.

I tried the ole db driver and got nowhere, couldn't even get a basic
connection. Hopefully I can get this corrected and work with this
driver a little bit. I have about two weeks to figure out the best way
to proceed. So far, I'm really unimpressed with the ado architecture,
this being my first real experience with it (as compared to ado.net,
which is a dream to work with).
