how to list privileges on the database object itself via SQL?

["Wetmore, Matthew (CTR)" <Matthew.Wetmore@xxxxxxxxxxxxxxxxxxx>]

May I suggest PgAdmin GUI

Tom, 

Thanks for that.  It still seems rather weird that there isn't a more straightforward way to get access to that information.

 

Also the SQL generated by psql -E doesn't seem to work on earlier versions of PostgreSQL:

SELECT d.datname as "Name",
       pg_catalog.pg_get_userbyid(d.datdba) as "Owner",
       pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding",
       d.datcollate as "Collate",
       d.datctype as "Ctype",

-- start this section works in pg15, but not in pg11
       d.daticulocale as "ICU Locale",
       CASE d.datlocprovider WHEN 'c' THEN 'libc' WHEN 'i' THEN 'icu' END AS "Locale Provider",

-- end this section works in pg15, but not in pg11
       pg_catalog.array_to_string(d.datacl, E'\n') AS "Access privileges"
FROM pg_catalog.pg_database d
ORDER BY 1;

 

Even then, the results are a potentially very long concatenated string, or originally an array, in the "Access privileges" column.

 

Are you sure there isn't a more straightforward way to access this information?  Are you saying that the only place this information is stored is in an array in the datacl column of the pg_catalog.pg_database table?

If that's the case then I am going to be forced to either write code to parse out that array, or write a looping union of multiple "has_database_privilege()" calls.

 

Either case seems like overkill to get such basic information out of PostgreSQL....

 

rik.

psql is still a useful reference.  Run it with the -E option and
look at the SQL it issues when you say "\l".  Trim to fit your
requirements.
