Given exactly that mistake, I get

LOG:  invalid connection type "w"
CONTEXT:  line 1 of configuration file 
"/home/postgres/testversion/data/pg_hba.conf"
FATAL:  could not load pg_hba.conf

Are you sure you're looking in the right place?

One thought that comes to mind is that I've seen cases where SELinux
prevented the postmaster from writing anything at all to its stderr.
I didn't think that could still happen in any current SELinux versions,
but it might be worth checking the kernel log for avc denials.

That mistake looks familiar ;)

Err, please try putting an extra char before the first comment line,
like:

No, I can't.  I get something like this on stderr:

LOG:  invalid connection type "zlocal"
CONTEXT:  line 82 of configuration file 
"/home/postgres/testversion/data/pg_hba.conf"
FATAL:  could not load pg_hba.conf

I tried to start postmaster with:

* pg_ctl -D data start
* postmaster -D data
* pg_ctl -D data -l logfile start

None of them logged anything to anywhere. You can reproduce it on your
machine, too.

That information would certainly be logged somewhere.  Maybe you looked
in the wrong log file?  Or you're using one of those configurations
where early output to stderr goes to /dev/null?

[HACKERS] Cannot *start* server because of a typo in pg_hba.conf

2011-02-20 Thread Devrim GÜNDÜZ

Yesterday I spent about half an hour to dig an issue on my laptop -- 9.0
instance did not start, and there were nothing in the logs. Eventually I
straced postmaster on start, and noticed an extra char in the
pg_hba.conf, which caused postmaster not to start.

Is it possible to drop something to (startup) log file and mention about
the syntax error in hba file?

(FWIW, I saw the same issue in a Greenplum 4.0.3 instance 2 months
before or so.)
