SLONIK EVENT CONFIRMATION BEHAVIOUR
Slonik does not wait for event confirmations before performing this
This command was introduced in Slony-I 1.0
Any mismatch between slonik(1) and the C libraries ``living'' in the
PostgreSQL installation will result in this failing to do what is
expected, and, more than likely, failing to run at all. You may think
you are upgrading to version 1.1.5, but if you are running slonik(1)
from version 1.1.2, or if you didn't restart the database with a
version that has 1.1.5 libraries, and instead are referencing C stored
functions from version 1.1.1, the attempt to upgrade will fail, because
the sets of C functions have regularly changed between major versions.
Before Slony-I 1.2, the error messages that would result would be not
terribly informative; what you'd find, in PostgreSQL logs, is some
error message about being unable to load some stored function that
happens to be implemented in C. As of 1.2, one of the first things
done is to load a stored function to verify version numbers; it
complains in a much more direct fashion if you have some versioning
