Agreed.

 On my side, that's up to you Fujii-san. The patch does what it states, I
 only think that this extra 0 should be added either everywhere or nowhere.

Yep. I added extra 0 everywhere.

Ok, I just applied the patch. Thanks for the review!

 Not mandatory either: drop test_param_unit in the regression tests after
 running the test queries.

I don't have strong opinion about this. There are many tables which
regression test creates but doesn't drop. But if you strongly think that
the table must be dropped, I'm OK with that.

This remark is just to limit the amount of trash in the database used
for regression tests. But then if we'd remove everything we would lack
handy material for tests on utilities like database-wide thingies of
the type VACUUM, REINDEX, pg_dump, etc. And we can just drop the
database used for regressions to clean up everything. So that's not
mandatory at all. I tend to always clean up objects in my patches
touching regressions to limit interactions with other tests, but I
guess that's up to the person who wrote the code to decide.

Leaving lingering objects is not a bad thing, particularly if they have
unusual properties; they enable somebody pg_dump'ing the database which
can be a good test for pg_dump.

So you imply that the trailing zero (which the patch adds as flag)

Attached is the updated version of the patch.

 Except that, I tested as well the patch and it works as expected. The
 documentation, as well as the regression tests remain untouched, but I
 guess that this is fine (not seeing similar tests in regressions, and
 documentation does not specify the unit for a given parameter).

I think that it's worth adding the regression test for this feature.
Attached patch updates the regression test.

[HACKERS] Specifying the unit in storage parameter

2014-08-07 Thread Fujii Masao
Hi,

We can specify the unit when setting autovacuum_vacuum_cost_delay
GUC as follows.

ALTER SYSTEM SET autovacuum_vacuum_cost_delay TO '80ms';

OTOH we cannot specify the unit when setting autovacuum_vacuum_cost_delay
as storage parameter as follows.

CREATE TABLE test (col1 int) WITH (autovacuum_vacuum_cost_delay = '80ms');
ERROR:  invalid value for integer option
autovacuum_vacuum_cost_delay: 80ms

This is not user-friendly. I'd like to propose the attached patch which
introduces the infrastructure which allows us to specify the unit when
setting INTEGER storage parameter like autovacuum_vacuum_cost_delay.
Comment? Review?

No disagreement here.

 I'd like to propose the attached patch which

 Comment? Review?

Hm, what's with the parse_int signature change and the hintmsg thing?
Is it just me or the patch is incomplete?

 Hi,

 We can specify the unit when setting autovacuum_vacuum_cost_delay
 GUC as follows.

 ALTER SYSTEM SET autovacuum_vacuum_cost_delay TO '80ms';

 OTOH we cannot specify the unit when setting autovacuum_vacuum_cost_delay
 as storage parameter as follows.

 CREATE TABLE test (col1 int) WITH (autovacuum_vacuum_cost_delay = 
 '80ms');
 ERROR:  invalid value for integer option
 autovacuum_vacuum_cost_delay: 80ms

 This is not user-friendly.

 No disagreement here.

 I'd like to propose the attached patch which
 introduces the infrastructure which allows us to specify the unit when
 setting INTEGER storage parameter like autovacuum_vacuum_cost_delay.
 Comment? Review?

 Hm, what's with the parse_int signature change and the hintmsg thing?
 Is it just me or the patch is incomplete?

Sorry, probably I failed to see your point. You mean that the signature
of parse_int needs to be changed so that it includes the hintmsg as the
argument? If yes, there is no problem. Both signature and function body
of parse_int has already included the hingmsg as the argument so far.
Am I missing something?

I just mean that the parse_int function body is not touched by your
patch, unless I am failing to see something.

Yes, my patch doesn't change the parse_int function at all because I didn't
think such change is required for the purpose (i.e., just allows us to specify
the unit in the setting of storage parameters). But, you might find the
reason why it needs to be changed?
