Re: [HACKERS] Patch: Write Amplification Reduction Method (WARM)

Hi Pavan,

I run a test on current warm patchset, i used pgbench with a scale of
20 and a fillfactor of 90 and then start the pgbench run with 6
clients in parallel i also run sqlsmith on it.

And i got a core dump after sometime of those things running.

The assertion that fails is:

"""
LOG:  statement: UPDATE pgbench_tellers SET tbalance = tbalance + 3519
WHERE tid = 34;
TRAP: FailedAssertion("!(((bool) (((const void*)(&tup->t_ctid) !=
((void *)0)) && (((&tup->t_ctid)->ip_posid & ((((uint16) 1) << 13) -
1)) != 0))))", File: "../../../../src/include/access/htup_details.h",
Line: 659)
