Обсуждение: pgsql: Fix outdated comment

Fix outdated comment

Commit bc971f4025 replaced the latch-setting mechanism that the
comment talked about with a condition variable. And before that,
commit 2258e76f90 moved the code so that the comment got detached from
the loop that it talked about, so move the comment closer to the loop.
