I don't have particular preference here, but FWIW the current
PQuntrace is doing this:

Looking the doc mentioned in the comment #39:
+ <literal>flags</literal> contains flag bits describing the operating mode
+ of tracing. If (<literal>flags</literal> &
<literal>PQTRACE_OUTPUT_TIMESTAMPS</literal>) is
+ true, then timestamp is not printed with each message.
PQTRACE_OUTPUT_TIMESTAMPS is designed to *inhibit* timestamps from
being prepended. If that is actually intended, the symbol name should
be PQTRACE_NOOUTPUT_TIMESTAMP. Otherwise, the doc need to be fixed.
By the way removing "== 0" makes it difficult to tell whether the
condition is correct or not; I recommend to use '!= 0" rather than
removing '== 0'.
regards.
