Subject: @remove-line-for-nolocal@ is dead code
Date: Wed, 18 Feb 2026 18:42:37 -0500
Message-ID: <2287786.1771458157@sss.pgh.pa.us> (raw)
While poking at something else, I noticed that the logic in initdb
about removing "@remove-line-for-nolocal@" from pg_hba.conf is
useless. Since commit f55808828, it's applied unconditionally;
so we might as well just edit that out of pg_hba.conf.sample and
delete the code to do so during initdb.
This won't save any interesting number of cycles of course, but
I think it's confusing to have that decoration in pg_hba.conf.sample
when it doesn't do anything.
Any objection to the attached?
regards, tom lane
