Folks,
I noticed that there wasn't a bulk way to see table logged-ness in
psql, so I made it part of \dt+.
What say?
Best,
David.

Applies, compiles, works for me.
ISTM That temporary-ness is not shown either. Maybe the persistence column
should be shown as is?
Also I'd suggest that the column should be displayed before the
"description" column to keep the length-varying one last?

Tests? Doc?

Temporariness added, but not raw.

Done.

Included, but they're not stable for temp tables. I'm a little stumped
as to how to either stabilize them or test some other way.

What further documentation does it need?

Hmmm. First there is the username which appears, so there should be a
dedicated user for the test.
I'm unsure how to work around the temporary schema number, which is
undeterministic with parallel execution it. I'm afraid the only viable
approach is not to show temporary tables, too bad:-(

Indeed, there is no precise doc, so nothing to update :-)/:-(
Maybe you could consider adding a case for prior 9.1 version, something
like:
... case c.relistemp then 'temporary' else 'permanent' end as ...

I was reviewing this patch and found a bug,
create table t (i int);
create index idx on t(i);

Looking into this further, apparently the position of
if (verbose)
{
+ /*
+ * Show whether the table is permanent, temporary, or unlogged.
+ */
+ if (pset.sversion >= 91000)
+ appendPQExpBuffer(&buf,
+ ",\n case c.relpersistence when 'p' then 'permanent' when 't'
then 'temporary' when 'u' then 'unlogged' else 'unknown' end as
\"%s\"",
+ gettext_noop("Persistence"));
is not right, it is being called for indexes with verbose option also.
There should be an extra check for it being not called for index case.
Something like,
if (verbose)
{
/*
* Show whether the table is permanent, temporary, or unlogged.
*/
if (!showIndexes)
if (pset.sversion >= 91000)
appendPQExpBuffer(&buf,
",\n case c.relpersistence when 'p' then 'permanent' when 't' then
'temporary' when 'u' then 'unlogged' else 'unknown' end as \"%s\"",
gettext_noop("Persistence"));
Not sure, how do modify it in a more neat way.

I suspect that as this may get a little messier, but I've made it
fairly neat short of a major refactor.

I found the following warning on the compilation,
describe.c: In function ‘listTables’:
describe.c:3705:7: warning: this ‘if’ clause does not guard...
[-Wmisleading-indentation]
else if (pset.sversion >= 80100)
^~
describe.c:3710:3: note: ...this statement, but the latter is
misleadingly indented as if it were guarded by the ‘if’
appendPQExpBuffer(&buf,
Talking of indentation, you might want to run pgindent once. Other
than that the patch looks good to me.
