The previous discussion concluded that EXECUTE should return the command
tag of the executed command --- eg, "UPDATE n" not "EXECUTE n". Without
this, you cannot for example sensibly cope with both the INSERT and
UPDATE tag formats.
Not sure what it takes internally to the backend to make this happen
... but IIRC there already is provision for utility commands to override
their default tag, so I hope that it would be a pretty localized change.
However, does this really solve Kris' problem? JDBC generally likes to
think that it works with old Postgres versions; will a fix that only
works in >= 7.5 be good enough for them?
