I tested that situation with an small table many days ago.. Sort of:
create table test (a integer, b timestamp);
insert into test values (1, now());
when i stated "select b from test;" in every node, i got indeed slightly
different values, in thousandths of seconds..
Even more, when I executed the select through pgpool, it returned different
values on different sessions.. But pgpool anyway continued to work
normally.. I thought that it would detect the data mismatch and degrade one
of the nodes...
