libpq: Fix PQtrace() format for non-printable characters PQtrace() was generating its output for non-printable characters without casting the characters printed with unsigned char, leading to some extra "\xffffff" generated in the output due to the fact that char may be signed.
Oversights introduced by commit 198b3716dba6, so backpatch down to v14.
