Re: A local replication entry - Mailing list pgsql-admin

Well, it is using the pg_hba.conf I thought. I edited the pg_hba.conf file and changed the line I thought pg_basebackup
shouldbe using from "trust" to "fake_it" and issued a  
reload. I saw an "invalid authentication method 'fake_it'" reported in the pg_log/postgresql-Wed.log file. To confirm
thatit really was using the correct pg_hba.conf file and I  
stopped the database and tried to start it again. That start did fail with:

<timestamp> % LOG: invalid authentication method "fake_it"
<timestamp> % CONTEXT: line 101 of configuration file "/var/lib/pgsql/9.3/data/pg_hba.conf"
<timestamp> % FATAL: could not load pg_hba.conf

So, it really is using the correct pg_hba.conf.

Allow me to note, in closing, that this particular VM: csgha2 has been a problem child since it was built, and many
thingshave been broken on it. I don't know if this is another  
one of the very hard-to-solve problems or not. I may try this on another of my sandbox systems. Still I need to know
whythis is failing.
