Huh? I said speed is the problem, for which the timer partly helps by
seperating the query/transfer time from the display time. What are you
saying is the problem?

Agreed. There is no reason with a little work why both goals cannot be
met.

Yes, this is an old discussion. pgAdmin has *always*, since the very
first version aimed to provide data manipulation as well as querying
capabilities.

Agreed. Query Analyser does manage to do both quite well and is a good
benchmark to aim for IMNSHO.

Yes, I did, which is pretty much what I believe Andreas has also
suggested in the past.

*How* that is implemented is another issue. I suspect that Andreas means
he wants it encapsulated into ctlSqlResult, overriding the existing data
population methods, rather than an extra layer of complexity between the
data retreival code and ctlSqlResult.
