I would look at your PostgreSQL logs to see the exact crashing update statement that VB is sending to PostgreSQL to process (you may need to first turn on query logging in your postgresql.conf file and then restart your PostgreSQL service).  Next I would try to manually run the listed update query in postgres' command line editor psql to see the error message that it generates.  This will probably a very clear indication of what is wrong in your VB generated record-set update. 

Also, give the how-to example for using ADO + ODBC + PG a try that comes with your ODBC installation help documentation?
it is found in this path on my computer: 
C:\Program Files\PostgreSQL\8.2\doc\psqlODBC\howto-vb.html

Also, you may consider using the PostgreSQL Unicode ODBC driver over the ANSI driver since it supports a larger array of character sets.

I wish I could be of more help, but I've never really grown accustom to using Records sets to update or delete records.  I've always manually crafted my own SQL statements that I've passed to the back-end server.

Also at the risk of getting my head bitten off by someone more knowledgeable that disagrees :-), it is a good practice to know your database schema design well enough to know the names of your tables and columns.  It is also good practice to directly call out those column names in your code rather than simply guessing based on the field types.
