Output from strace can be somewhat esoteric, especially as it limits the content length by default to increase readability. If we want to really capture a lot of data with extreme verbosity that will help a human make a diagnosis, we need to increase the string length. For strace, the parameter for that is -s. If we wanted to greatly extend the length of the string output, we can do that with this command:
strace -p 4200 -s 2000
Then, if we execute the following query:
SELECT 'This is a very long query to view.';
We would see this output:
recvfrom(11, "Q\0\0\0001select 'This is a very long query to view.';\0", 8192, 0, NULL, NULL) = 50
Instead of this:
recvfrom(11, "Q\0\0\0001select 'This is a very long"..., 8192, 0, ...
