Pushed, with the tweaks to use FastPathLockSlotsPerBackend() in a couple
more places.
I noticed sifaka started failing right after I pushed this:
https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=sifaka&br=master
But I have no idea why would this cosmetic change cause issues with LDAP
tests, so I'm assuming the failure is unrelated, and the timing is
accidental and not caused by the patch.
