guc.c and postgresql.conf.sample constistency checker

This is a small script to check that guc.c and postgresql.conf.sample
are fairly representative of each other, and the output that I'm getting
against the most recent cvs.

The catch is that some of these options (lc_*) are supposed to be absent,
so it's not as easy as it seems.

The fix for debug_level is easy enough (I know it was removed from guc.c),
but I don't know enough about the rest of the items to be able to document
them in the postgresql.conf.sample well.

output:
debug_level seems to be missing from guc.c
fixbtree seems to be missing from postgresql.conf.sample
pre_auth_delay seems to be missing from postgresql.conf.sample
lc_messages seems to be missing from postgresql.conf.sample
lc_monetary seems to be missing from postgresql.conf.sample
lc_numeric seems to be missing from postgresql.conf.sample
lc_time seems to be missing from postgresql.conf.sample
server_encoding seems to be missing from postgresql.conf.sample
session_authorization seems to be missing from postgresql.conf.sample

I believe this script should live in src/tools
#!/bin/sh

## currently, this script makes a lot of assumptions:
## 1) location of guc.c and postgresql.conf.sample relative to src/tools
## For postgresql.conf.sample
## 2) the valid config settings may be preceded by a '#', but NOT '# '
## 3) the valid config settings will be followed immediately by ' ='
## (at least one space preceding the '='
## For guc.c
## 4) the options have PGC_ on the same line as the option
## 5) the options have '{ ' on the same line as the option

## Problems
## 1) Don't know what to do with TRANSACTION ISOLATION LEVEL (in guc.c)

PATH_TO_GUC="`dirname $0`/../backend/utils/misc"

SETTINGS=`grep ' =' $PATH_TO_GUC/postgresql.conf.sample | grep -v '^# ' | sed -e 's,^#,,' | awk '{print $1}'`
for i in $SETTINGS ; do
grep -i $i $PATH_TO_GUC/guc.c > /dev/null;
if [ ! $? = 0 ] ; then
echo "$i seems to be missing from guc.c";
fi;
done

SETTINGS=`grep '{ .*PGC_' $PATH_TO_GUC/guc.c | awk '{print $2}' | sed -e 's,",,g' -e 's/,//'`
for i in $SETTINGS ; do
grep -i $i $PATH_TO_GUC/postgresql.conf.sample > /dev/null;
if [ ! $? = 0 ] ; then
echo "$i seems to be missing from postgresql.conf.sample";
fi;
done

See subsequent objections from Peter and me. We could use something
like this, but it needs to be smarter.

Sorry I missed the objections. I will not apply the script.

What about the comments he makes about the missing postgresql.conf
entries. Do those need fixing?

debug_level seems to be missing from guc.c
fixbtree seems to be missing from postgresql.conf.sample
pre_auth_delay seems to be missing from postgresql.conf.sample
lc_messages seems to be missing from postgresql.conf.sample
lc_monetary seems to be missing from postgresql.conf.sample
lc_numeric seems to be missing from postgresql.conf.sample
lc_time seems to be missing from postgresql.conf.sample
server_encoding seems to be missing from postgresql.conf.sample
session_authorization seems to be missing from postgresql.conf.sample

debug_level is removed from postgresql.conf already, replaced by
client/server_min_messages.

No (with the exception of debug_level which you got already).
