Hi,

Another one caught by sqlsmith, on the regression database run this
query (using any non-partitioned table works fine):

"""
select currtid('pagg_tab'::regclass::oid, '(0,156)'::tid) >= '(1,158)'::tid;
"""

This works on 11 (well it gives an error because the file doesn't
exists) but crash the server on 12+

attached the stack trace from master
