Re: [PATCHES] Postgresql.conf Documentation change

I had a problem with this patch. By removing the comment from 'port',
the postgresql.conf 'port' value is used in the regression tests rather
than the environment value. I see in guc.c

env = getenv("PGPORT");
if (env != NULL)
SetConfigOption("port", env, PGC_POSTMASTER, PGC_S_ENV_VAR);

but, look at this:

typedef enum
{
PGC_S_DEFAULT, /* wired-in default */
PGC_S_ENV_VAR, /* postmaster environment variable */
PGC_S_FILE, /* postgresql.conf */
PGC_S_ARGV, /* postmaster command line */
PGC_S_UNPRIVILEGED, /* dividing line for USERLIMIT */
PGC_S_DATABASE, /* per-database setting */
PGC_S_USER, /* per-user setting */
PGC_S_CLIENT, /* from client connection request */
PGC_S_OVERRIDE, /* special case to forcibly set default */
PGC_S_INTERACTIVE, /* dividing line for error reporting */
PGC_S_TEST, /* test per-database or per-user setting */
PGC_S_SESSION /* SET command */
} GucSource;

which says that the config file value overrides the environment value.
By removing comments from postgresql.conf, I am afraid we are making all
environment value useless.

I suppose the easiest fix would be to re-command the postgresql.conf
values that can be over-ridden with environment variables, or make
environment variables more significant than postgresql.conf values, and,
being in beta, which should we do now and which should we do for 8.1?

Comments?
