Hi,
I've started looking at the patch over the past few days. I don't have
any deep insights at this point, but there seems to be some sort of
issue in pgstat_update_stat. When building using gcc, I do get this warning:
pgstat.c: In function ‘pgstat_update_stat’:
pgstat.c:648:18: warning: ‘now’ may be used uninitialized in this
function [-Wmaybe-uninitialized]
oldest_pending = now;
~~~~~~~~~~~~~~~^~~~~
PostgreSQL installation complete.
which kinda makes sense, because 'now' is set only in the (!force)
branch. So if the very first call to pgstat_update_stat is with
force=true, it's not set, and the code executes this:
/* record oldest pending update time */
if (pgStatPendingTabHash == NULL)
oldest_pending = 0;
else if (oldest_pending == 0)
oldest_pending = now;
at which point we set "oldest_pending = now" with "now" containing some
random garbage.
When running this under valgrind, I get a couple of warnings in this
area of code - see the attached log with a small sample. Judging by the
locations I assume those are related to the same issue, but I have not
looked into that.
regards
