That worked - and I see has already been committed, thanks.
There is another small issue related to this dumping into a readonly slave:
With multiline columns (at least, I think that's the reason),
there are on STDERR endless occurrences of:
invalid command \N
and
invalid command \
There can be millions of these lines (obviously).
On top of that, the logfile gets appended
with 'syntax error', follwed by the whole dump:
ERROR: syntax error at or near "18726" at character 1
STATEMENT: 18726 16883 [...] [whole dump follows here]
This does maybe not really qualify as a bug, but it does
seem unnecessary to spam a readonly standby with all
this. (come to think of it, 'syntax error' is a bit off in any case)
Thanks,
Erik Rijkers
