I have started to have a look at the feature and review the patch, my initial comments: 1) I could specify invalid subscriber id to pg_stat_reset_subscription_worker which creates an assertion failure? +static void +pgstat_recv_resetsubworkercounter(PgStat_MsgResetsubworkercounter *msg, int len) +{ + PgStat_StatSubWorkerEntry *wentry; + + Assert(OidIsValid(msg->m_subid)); + + /* Get subscription worker stats */ + wentry = pgstat_get_subworker_entry(msg->m_subid, msg->m_subrelid, false); postgres=# select pg_stat_reset_subscription_worker(NULL, NULL); pg_stat_reset_subscription_worker ----------------------------------- (1 row) TRAP: FailedAssertion("OidIsValid(msg->m_subid)", File: "pgstat.c", Line: 5742, PID: 789588) postgres: stats collector (ExceptionalCondition+0xd0)[0x55d33bba4778] postgres: stats collector (+0x545a43)[0x55d33b90aa43] postgres: stats collector (+0x541fad)[0x55d33b906fad] postgres: stats collector (pgstat_start+0xdd)[0x55d33b9020e1] postgres: stats collector (+0x54ae0c)[0x55d33b90fe0c] /lib/x86_64-linux-gnu/libpthread.so.0(+0x141f0)[0x7f8509ccc1f0] /lib/x86_64-linux-gnu/libc.so.6(__select+0x57)[0x7f8509a78ac7] postgres: stats collector (+0x548cab)[0x55d33b90dcab] postgres: stats collector (PostmasterMain+0x134c)[0x55d33b90d5c6] postgres: stats collector (+0x43b8be)[0x55d33b8008be] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xd5)[0x7f8509992565] postgres: stats collector (_start+0x2e)[0x55d33b48e4fe] 2) I was able to provide invalid relation id for pg_stat_reset_subscription_worker?
