"revdberr, " as the returned value on *successful* postgres operations

Is it reliably reproducible?  You said:  "I've also seen the same issue
with single transactions outside of BEGIN
When using the same data, same single transaction, do you get the same
result every time?  Does changing the data change the response?  If a
specific set of conditions can be tracked down that cause the issue it
would be a huge step towards a solve.

Also i'm wondering, if you make the changes, do the commit,
then immediately select the same records, have they all been successfully
updated?  I don't know enough about how postges works to be sure but either
a)  (ignoring the fact that single statements sometimes do this) if a
begin/commit block has a problem with a statement, then postgres may treat
it as an atomic transaction (1 fails all fail) and autorollback, or b) its
informing you that there was an issue in there somewhere and giving you the
option to rollback yourself.

You might, short term, remove the begin/commit, and use a repeat to loop
through each sql statement, logging the sql used for each, the values being
passed in, and whether or not there was an error. Even if you do this one
single time, if you get a viewable error, its worth the time involved. And
if you don't, that might be informative too.  If there are LOTS of
transactions to be done this will be considerably slower, but may be

Sorry, was typing and thinking as you were answering.  Yeah, it
will CONSIDERABLY slow down your transactions to use the 1 at a time
method, but if you can do it with a small dataset to track down the issue
it might be worth it.  My worry would be that there is actually a real
reason you're getting this error rather than a strange glitchy thingy that
can be safely ignored.
