If you really think that you have discovered a memory leak with a simple scenario as that could you please open a new bugreport on report your findings there instead of hiding it deep in other threads.

[BUGS] BUG #6353: If there is invalid line in pg_hba.conf, DB start fails without any nofice and no logs in pgstartup.
The following bug has been logged on the website: Bug reference: 6353 Logged by: Erkan Durmus Email address: er...@eurotel.com.tr PostgreSQL version: 9.0.6 Operating system: Centos 5.7 Description: Hi, Firstly, thanks for developing Pgsql! Problem: If I add this line to pg_hba.conf, it causes a silent startup failure: localallbackup 127.0.0.1/32 trust There is a linux user backup on this system. After adding this line and issue "pg_ctl reload" it signals server successfully, no errors. But if I stop db server, I can not start db anymore. Strangely no log exists in pgstartup.log. Even I start with -d 5 debug param, it exists after "logging shutdown" message. Debugging with gdb didn't help. After removing the line added above in pg_hba.conf, db starts.

This didn't use to be allowed at all before 9.0; previous releases would reject the index definition: regression=# CREATE INDEX tab123 ON tab (a, b, a); ERROR: duplicate key value violates unique constraint "pg_attribute_relid_attnam_index" But now that we allow it it'd be nice if it actually worked :-(. Looking into the archives I see that we were mainly thinking about the possibility of exclusion constraints naming the same column more than once, which may explain why nobody tried using such an index for queries. I'll see about fixing this in HEAD, although my initial guess is that it will be too invasive to back-patch. regards, tom lane -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

Did you check your server logs (pgstartup.log must be the pg_ctl output)? I got: LOG: invalid authentication method "127.0.0.1/32" CONTEXT: line 80 of configuration file "/home/euler/pg90/data/pg_hba.conf" FATAL: could not load pg_hba.conf If you don't have logging_collector enabled, you should get the above message in your terminal. Problem is: instead of local you should use host. -- Euler Taveira de Oliveira - Timbira http://www.timbira.com.br/ PostgreSQL: Consultoria, Desenvolvimento, Suporte 24x7 e Treinamento -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

Well, that line is obviously incorrect, because a "local" line doesn't need an IP address. For me, the postmaster gives very clear warnings about this, either in the pg_ctl reload case: LOG: received SIGHUP, reloading configuration files LOG: invalid authentication method "127.0.0.1/32" CONTEXT: line 95 of configuration file "/var/lib/pgsql/data/pg_hba.conf" WARNING: pg_hba.conf not reloaded or in the fresh-start case: LOG: invalid authentication method "127.0.0.1/32" CONTEXT: line 95 of configuration file "/var/lib/pgsql/data/pg_hba.conf" FATAL: could not load pg_hba.conf Your problem apparently is that the log messages are either not coming out at all, or you're looking in the wrong place for them. You have not said anything about your logging configuration so it's hard to give concrete advice, but in the default configuration set up by Red Hat's packages I'd expect those messages to appear in the current log file underneath /var/lib/pgsql/data/pg_log/. It's also conceivable that the messages aren't getting out at all because of a permissions-type problem --- I remember some very old versions of selinux policy would sometimes block postgres log messages, for example. If you've got selinux enabled it'd be worth checking for avc messages in the kernel logs. regards, tom lane -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
