I have a different but possibly-related complaint: why is
040_pg_createsubscriber.pl so miserably slow? On my machine it
runs for a bit over 19 seconds, which seems completely out of line
(for comparison, 010_pg_basebackup.pl takes 6 seconds, and the
other test scripts in this directory take much less). It looks
like most of the blame falls on this step:
[12:47:22.292](14.534s) ok 28 - run pg_createsubscriber on node S
AFAICS the amount of data being replicated is completely trivial,
so that it doesn't make any sense for this to take so long --- and
if it does, that suggests that this tool will be impossibly slow
for production use. But I suspect there is a logic flaw causing
this. Speculating wildly, perhaps that is related to the failure
Alexander spotted?
