pgsql: Revert accidental change to pg_config_manual.h.

Revert accidental change to pg_config_manual.h.

This was broken in commit 53dbc27c62d8e1b6c5253feba04a5094cb8fe046, which
introduced unlogged tables.  Fortunately, as debugging tools go, this one
is pretty cheap, which is probably why it took nine months for someone to
notice, but it's not intended to be enabled by default, so revert.
