Hi,
I've committed this, with some minor documentation tweaks. I've also
fixed a minor bug in the last patch, where the group with settings was
not properly labeled in some formats (e.g. json).
Thanks to all the reviewers!
regards

Could you fix your patch then? I am moving it to next CF, waiting on

Ok, looks good. I tried changing config values with the .conf file,
alter system, and alter database, and tried a few queries with
auto_explain. I made a pass through the

Hi Tomas,
Peter suggested upthread to use 'settings' rather than 'gucs' for the
explain option (and output?), and you seemed to agree. Are you going
to include that in a future version? Speaking of the output, v5's
default text doesn't match that of formatted text ('GUCs' / 'GUC').

Hi,
every now and then I have to investigate an execution plan that is
strange in some way and I can't reproduce the same behavior. Usually
it's simply due to data distribution changing since the problem was
observed (say, after a nightly batch load/update).
In many cases it however may be due

Attached is v4, changing how GUCs are picked for inclusion on the query
plans. Instead of picking the GUCs based on group and/or explicitly, a
new GUC_EXPLAIN flag is used for that.
I went through GUCs defined in guc.c and marked those in QUERY_TUNING*
groups accordingly, with the exception of

Yeah, I've been thinking about that too. Currently it gets filtered out
because it's in the CLIENT_CONN_STATEMENT group, but the code only
includes QUERY_TUNING_*.
But we

I'm a bit suspicious about whether this'll have any actual value,
if it's disabled by default
