first: thanks for your fast answer.

if had found it in the manual but there is only a short clause about
this topic:

"Abort any statement that takes over the specified number of
milliseconds. A value of zero (the default) turns off the limitation. "

( by the way in my config file is it set to zero by default and that
means that it will be wait without a timeout.
#statement_timeout = 0        # 0 is disabled, in milliseconds
)

so but i'm not sure, doesn't it mean that all statements that take
longer than this time will be abort?
if it is so, that isn't a solution for this problem because than i can't
make a "big" request anymore.
