commit    3d185cfc09c32b1f250adfbb62c0c7a3f96c5af2
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Wed Jan 10 23:09:29 2024 +0000
First released in: 17.0, 16.2

    Restore initdb's old behavior of always setting the lc_xxx GUCs.
    
    In commit 3e51b278d I (tgl) caused initdb to leave lc_messages and
    other lc_xxx GUCs commented-out in the installed postgresql.conf file
    if they were going to be set to 'C'.  This was a hack for cosmetic
    purposes, and it was buggy because lc_messages' wired-in default is
    not 'C' but '' (empty string).  That led to --no-locale not having
    the expected effect, since the postmaster would then obtain
    lc_messages from its startup environment.
    
    Let's just revert to the prior behavior of always de-commenting the
    lc_xxx entries; the argument for changing that longstanding behavior
    was weak in the first place.
    
    Also, fix postgresql.conf.sample's erroneous claim that the default
    value of lc_messages is 'C'.  I suspect that was what misled me into
    making this mistake in the first place.
    
    Report and patch by Kyotaro Horiguchi.  Back-patch to v16 where
    the problem was introduced.
