Thread: pgsql: Restore lock level to set vacuum flags

Restore lock level to set vacuum flags

Commit 27838981be9d mistakenly reduced the lock level from exclusive to
shared that is acquired to set PGPROC->statusFlags; this was reverted
by dcfff74fb166, but failed to do so in one spot.  Fix it.

Backpatch to 14.
