..but it doesn't seem worth factoring out the common bits, since stat_file
doesn't return a name, so all the field numbers are off by one.
NOTE, the atime is now shown where the mtime used to be.
Need catversion bump

* Fix output of zero privileges in psql
@ 2023-09-17 19:31 Erik Wienhold <[email protected]>

To: PostgreSQL Hackers <[email protected]>
I wrote a patch to change psql's display of zero privileges after a user's
reported confusion with the psql output for zero vs. default privileges [1].
Admittedly, zero privileges is a rare use case [2] but I think psql should not
confuse the user in the off chance that this happens.
With this change psql now prints "(none)" for zero privileges instead of
nothing. This affects the following meta commands:
\db+ \dD+ \df+ \dL+ \dl+ \dn+ \dp \dT+ \l
Default privileges start as NULL::aclitem[] in various catalog columns but
revoking the default privileges leaves an empty aclitem array. Using
\pset null '(null)' as a workaround to spot default privileges does not work
because the meta commands ignore this setting.
The privileges shown by \dconfig+ and \ddp as well as the column privileges
shown by \dp are not affected by this change because those privileges are reset
to NULL instead of leaving empty arrays.
Commands \des+ and \dew+ are not covered in src/test/regress because no foreign
data wrapper is available at this point to create a foreign server.

Subject: [PATCH v1] Fix output of zero privileges in psql
Print "(none)" for zero privileges instead of nothing so that the user
is able to distinguish zero from default privileges. This affects the
following meta commands:
\db+ \dD+ \des+ \dew+ \df+ \dL+ \dl+ \dn+ \dp \dT+ \l
Default privileges start as NULL::aclitem[] in various catalog columns
but revoking the default privileges leaves an empty aclitem array.
Using \pset null '(null)' as a workaround to spot default privileges
does not work because the meta commands ignore this setting.
The privileges shown by \dconfig+ and \ddp as well as the column
privileges shown by \dp are not affected by this change because those
privileges are reset to NULL instead of leaving empty arrays.
Commands \des+ and \dew+ are not covered in src/test/regress because no
foreign data wrapper is available at this point to create a foreign
server.

Reading that thread, I had the impression that there was more support for
honoring "\pset null" rather than unconditionally displaying "(none)".
The simple attached patch does it like that. What do you think?

Subject: [PATCH] psql: honor "\pset null" in backslash commands
In the output of backslash commands, NULL was always displayed
as empty string, rather than honoring the values set with
"\pset null".
This was surprising, and in some cases it was downright confusing:
for example, default privileges (stored as NULL) were displayed
just like an empty aclitem[], making these cases undistinguishable
in the output.

I took Tom's response in the -general thread to mean that we could fix
\pset null also as a "nice to have" but not as a solution to the display
of zero privileges.
Only fixing \pset null has one drawback IMO because it only affects how
default privileges (more common) are printed. The edge case of zero
privileges (less common) gets lost in a bunch of NULL output. And I
assume most users change the default \pset null to some non-empty string
in their psqlrc (I do).
For example with your patch applied:
create table t1 (a int);
create table t2 (a int);
create table t3 (a int);
revoke all on t2 from :USER;
\pset null <NULL>
\dp t1|t2|t3
Access privileges
Schema | Name | Type | Access privileges | Column privileges | Policies
--------+------+-------+-------------------+-------------------+----------
public | t1 | table | <NULL> | |
public | t2 | table | | |
public | t3 | table | <NULL> | |
(3 rows)
Instead of only displaying the zero privileges with my patch and default
\pset null:
\pset null ''
\dp t1|t2|t3
Access privileges
Schema | Name | Type | Access privileges | Column privileges | Policies
--------+------+-------+-------------------+-------------------+----------
public | t1 | table | | |
public | t2 | table | (none) | |
public | t3 | table | | |
(3 rows)
I guess if most tables have any non-default privileges then both
solutions are equally good.

LGTM.
