I agree that debug levels are not suitable for this.
Squid (the (reverse) proxy) has a nice feature for debugging purposes
(admin and developers). It's possible to have different logging level
for different sections of the code. For example, if you want to debug
a particular part, you can have ALL,1 33,2 in your config file which
allows you to have a more verbose debug on the section 33 of the code
(33 is ACL).
It's really useful because you can even debug a particular code path
or a misconfiguration in production without generating a huge amount
of logs.
Yes, that'd be really nice, though using numeric codes is a bit archaic.
In Java-world, a logging framework called log4j has become the de facto
standard to implement logging. It's basically the same idea, you have
different log levels, and you can have enable different levels of
logging for different modules. I'm sure there's similar libraries for C,
that's something to think about in future releases.
8.3 will add some new log_* GUC variables, log_autovacuum and
log_temp_files, so it seems we're headed to that direction already. I'm
now thinking that's the approach we should take for checkpoints as well:
add a new GUC variable, log_checkpoints, and print the messages at
LOG-level if that's enabled.
