Hi Alvaro,

It would be good to see the contents of MultiXactState.  I suspect
there's a race condition in the MultiXact code.

Good, but... where do I find the contents of MultiXactState? ;)


Huh, it should be a global variable.  Try

p *MultiXactState


Done:

(gdb) p *MultiXactState

$1 = {nextMXact = 320308, nextOffset = 4235265, lastTruncationPoint =302016, perBackendXactIds = {0}}



Best regards
