Server passed 'make check' with this patch, but when I tried to fire
it up for some test runs, it fell over with:

FATAL:  no more LWLockIds available

I assume that it must be dependent on the config settings used.  Here are mine:

shared_buffers = 8GB
maintenance_work_mem = 1GB
synchronous_commit = off
checkpoint_segments = 300
checkpoint_timeout = 15min
checkpoint_completion_target = 0.9
wal_writer_delay = 20ms
