[HACKERS] A couple of postgresql.conf.sample discrepancies

Hi hackers,

Here's a script that reminds you about GUCs you forgot to put in
postgresql.conf.sample.  It probably needs some work.  Does this
already happen somewhere else?  I guess not, because it found two
discrepancies:

$ ./src/tools/check_sample_config.pl
enable_gathermerge appears in guc.c but not in postgresql.conf.sample
trace_recovery_messages appears in guc.c but not in postgresql.conf.sample

I think the first should be listed in postgresql.conf.sample, but the
second should probably be flagged as GUC_NOT_IN_SAMPLE.  See attached.

I like the idea. However maybe it worth considering to turn it into a
TAP test? Otherwise there is a good chance everybody will forget to run
it. For similar reason I would advise to add this patch to the next
commitfest.

Bonus points if the script can detect that a parameter's comment
forgets to include "(change requires restart)".

Instead of adding it to a TAP test, I think we should add it to the
build process, so you get a compile failure if it finds any problems.
