I guess we'll have to just #define it ourselves. Or could we just pick 
another magic value, do we actually rely on InvalidSerCommitSeqno being 
higher than all other values anywhere?

Hmm, it seems to choose a smaller max_connections value now, 20 instead 
of 30. Looks like our shared memory usage went up by just enough to pass 
that threshold.

Looks like our shared memory footprint grew by about 2MB with default 
configuration, from 37MB to 39MB. That's quite significant. Should we 
dial down the default of max_predicate_locks_per_transaction? Or tweak 
the sizing of the hash tables somehow?
