I deal with a number of PG databases on a number of sites, and it is a

set up the system.

You realize that the actual code feature doesn't necessarily help this
case, right? Putting configuration in /etc and having a configuration file
option on the command line are separate concepts.

I think the feature is worthwhile, but I have some initial condition
functionality questions that may have been answered in the previous patch,
but I don't remember at this point.

Mostly these have to deal with initial creation.  Does the user specify an
output location to initdb, do they just specify a data dir as now where
the configuration goes but then they need to move it somewhere, does
initdb now do nothing relating to configuration file and the user should
make one on his own.  Related, is the admin expected to have already made
(say) /etc/postgresql to stick the config in and set the permissions
correctly (since initdb doesn't run as root)?
My patch only works on the PostgreSQL server code. No changes have been made to the initialization scripts.

The patch declares three extra configuration file parameters:
hbafile= '/etc/postgres/pg_hba.conf'

The command line option is a capital 'C,' as in:
postmaster -C /etc/postgresql.conf

I have no problem leaving the default configuration files remaining in the data directory as sort of a maintenance / boot strap sort of thing, so I don't see any reason to alter the installation.

As for this feature helping or not, I think it will. I think it accomplishes two things:
(1) Separates configuration from data.
(2) Allows an administrator to create a convention across multiple systems regardless of the location and mount points of the database storage.
(3) Lastly, it is a familiar methodology to DBAs not familiar with PostgreSQL.

Again, I don't see a valid reason for not including the patch. Yes, if you don't want to configure PostgreSQL that way, then so be it, but why not add the functionality for those who do?

I can envision the configuration file methodology of managing a database becoming the "preferred" approach over time as it is a more familiar and standard way of configuring servers on UNIX.
