bug on log generation ?

I have to fix log files because its content is not properly formatted, I´m
using version 14.4 but that happened when I was using version 11 too. It
happens only when that statement is huge, or because it is a long sequence
of updates in a WITH or DO statements, or because i´m updating a bytea
field. This kind of statement occurs on log dozens of times a day, but just
2 or 3 are wrongly formatted.

one example is a WITH statement with dozens of inserts and updates on it

if you search for "$vs$Paga2022-08-06 10:07:07.505" you´ll see that
"$vs$Paga" is still part of first statement but "2022-08-06 10:07:07.505"
is the starting of next statement, but there are some missing chars of
previous statement.

another example is just one update with a large bytea field on it

Here "4445583e32022-08-06 15:58:42.436", where bytea content "4445583e" was
being displayed and the next statement started with "32022-08-06
15:58:42.436".

Obviously because that the previous line is not finished correctly and I
cannot import log files properly, so I have to edit those log files to
properly import them.

thanks
