On the one hand, this sounds better for me too. On the other hand,
will not
this be in some kind of conflict with error level codes in elog.h?..
I think it shouldn't because those error levels are backends levels.
pgbench is a client side utility with its own code, it shares some code
with libpq and other utilities, but elog.h isn't one of them.
I agree with you on this :) I just meant that maybe it would be better
to call this group in the same way because they are used in general for
the same purpose?..

About the name "log" - we already have the function doLog, so perhaps
the
name "report" will be better.. But like with ErrorLevel will not this
be in
some kind of conflict with ereport which is also used for the levels
DEBUG... / LOG / INFO?
+1 from me to keep initial name "pgbench_error". "pgbench_log" for new
function looks nice to me. I think it is better than just "log",
because "log" may conflict with natural logarithmic function (see "man
3
log").
Do you think that pgbench_log (or another whose name speaks only about
logging) will look good, for example, with FATAL? Because this means
that the logging function also processes errors and calls exit(1) if
necessary..
> pgbench_error calls pgbench_error. Hmmm, why not.
I agree with Fabien. Calling pgbench_error() inside pgbench_error()
could be dangerous. I think "fmt" checking could be removed, or we may
use Assert()
I would like not to use Assert in this case because IIUC they are mostly
used for testing.
or fprintf()+exit(1) at least.
Ok!
