Hi Pavan,
Today i was playing with your patch and running some tests and found
some problems i wanted to report before i forget them ;)
* You need to add a prototype in src/backend/utils/adt/pgstatfuncs.c:
extern Datum pg_stat_get_tuples_warm_updated(PG_FUNCTION_ARGS);
* The isolation test for partial_index fails (attached the regression.diffs)
* running a home-made test i have at hand i got this assertion:
"""
TRAP: FailedAssertion("!(buf_state & (1U << 24))", File: "bufmgr.c", Line: 837)
LOG: server process (PID 18986) was terminated by signal 6: Aborted
"""
To reproduce:
1) run prepare_test.sql
2) then run the following pgbench command (sql scripts attached):
pgbench -c 24 -j 24 -T 600 -n -f inserts.sql@15 -f updates_1.sql@20 -f
updates_2.sql@20 -f deletes.sql@45 db_test
* sometimes when i have made the server crash the attempt to recovery
fails with this assertion:
"""
LOG: database system was not properly shut down; automatic recovery in progress
LOG: redo starts at 0/157F970
TRAP: FailedAssertion("!(!warm_update)", File: "heapam.c", Line: 8924)
LOG: startup process (PID 14031) was terminated by signal 6: Aborted
LOG: aborting startup due to startup process failure
"""
still cannot reproduce this one consistently but happens often enough
will continue playing with it...
