Thread: Multiline privileges in \z
Hi hackers,
It occurred to me that psql's \z command could benefit from the
addition of some newlines. With any more than one grantee per object,
the output of \z rapidly becomes extremely wide, and very hard to
read.
I'd like to split the output onto one line per grantee. So, instead of this:
Schema | Name | Type | Access privileges
--------+------+-------+-------------------------------------------------------------------------
public | a | table |
{brendanjurd=arwdxt/brendanjurd,foo=arwd/brendanjurd,bar=r/brendanjurd}
public | b | table | {brendanjurd=arwdxt/brendanjurd,foo=arwd/brendanjurd}
(2 rows)
You would get this:
Schema | Name | Type | Access privileges
--------+------+-------+--------------------------------
public | a | table | brendanjurd=arwdxt/brendanjurd
: foo=arwd/brendanjurd
: bar=r/brendanjurd
public | b | table | brendanjurd=arwdxt/brendanjurd
: foo=arwd/brendanjurd
(2 rows)

are stored as an array, the patch to achieve this is trivial (see attached).
Looking forward to your comments.
Added to wiki.

Seems like a good idea now that psql deals nicely with multiline output.
The function names in the patch need schema-qualification in case
pg_catalog is not first in the search path.

Wouldn't this expression:
pg_catalog.array_to_string(c.relacl, chr(10))
be better expressed as
pg_catalog.array_to_string(c.relacl, E'\n')
?
Quoted inside a C literal, the backslash would have to be doubled, of course.

+1 ... it's minor, but knowing that ASCII LF is 10 is probably not
wired into too many people's brains anymore. (Besides, some of us
remember it as octal 12, anyway...)

I just wanted a non-messy way of saying "1 newline, please", and I wasn't too sure whether backslash escapes were considered kosher for internal queries. But you're right, readability is important. No objections to using the escape syntax. Please note that I used chr(10) in my \du attributes patch as well.
