Neiter LOG ERRORS nor REJECT LIMIT are implemented in PostgreSQL,
though I agree they may be useful. Both can be simulated with a custom
stored procedure which loops over a cursor and updates row-by-row,
trapping errors along the way. This will, of course, be slower.

Not as much as I first hoped. In hindsight it was a silly question.
The point was that the view gets linked into an Access-Client.
There are some Users who shouldn't bother to figure over the results as
it does some performance statistics.

How often are you using the bank balance value?
I have no data on this as of yet, but it obviously needs to be correct
for when the user looks at it.

Please disregard my other message. I didn't get what you are trying to
do at first.
You can do this with dynamic SQL: Look at 38.5.4. Executing Dynamic
Commands (http://www.postgresql.org/docs/current/static/plpgsql-
statements.html).
I guess something like
EXECUTE 'SELECT tmprec.group' || i
If you need them one by one why fetch them into tmprec? Take a look at
the docs for FETCH:
http://www.postgresql.org/docs/8.3/static/sql-fetch.html
especially the FETCH ABSOLUTE...

There are two things about cursors you may need to remember ( I hope I
