Great question - I thought of it myself but then forgot to look..

$ rpm -q postgresql1{2,3}-server
postgresql12-server-12.4-1PGDG.rhel7.x86_64
postgresql13-server-13-beta3_1PGDG.rhel7.x86_64

$ /usr/pgsql-12/bin/pg_config |grep -o cassert || echo not found
not found
$ /usr/pgsql-13/bin/pg_config |grep -o cassert || echo not found
cassert

It looks like the beta packages are compiled with cassert, which makes sense.

Thanks and sorry for noise.
