Hi,
I started to look at this patch and i found that it fails an assertion
as soon as you run a VACUUM FULL after a lazy VACUUM even if those are
on unrelated relations. For example in an assert-enabled build with
the regression database run:
VACUUM customer;
[... insert here whatever commands you like or nothing at all ...]
VACUUM FULL tenk1;
TRAP: FailedAssertion("!(InRecovery || ( ((void) ((bool) ((!
assert_enabled) || ! (!((heapBuf) <= NBuffers && (heapBuf) >=
-NLocBuffer)) || (ExceptionalCondition("!((heapBuf) <= NBuffers &&
(heapBuf) >= -NLocBuffer)", ("FailedAssertion"), "visibilitymap.c",
260), 0)))), (heapBuf) != 0 ))", File: "visibilitymap.c", Line: 260)
LOG: server process (PID 25842) was terminated by signal 6: Aborted
DETAIL: Failed process was running: vacuum FULL customer;
LOG: terminating any other active server processes
