Description

This function lists the users with access to a PostgreSQL® database.


Warning:

We strongly recommend that you use UAPI instead of cPanel API 2. However, no equivalent UAPI function exists.

Important:

In cPanel & WHM version 76 and later, when you disable the Postgres role, the system disables this function. For more information, read our How to Use Server Profiles documentation.

Examples

 LiveAPI PHP Class
$cpanel = new CPANEL(); // Connect to cPanel - only do this once.
 
// Generate a list of Postgres database users with access to "example_database"
$list_pgusers = $cpanel->api2(
    'Postgres', 'listusersindb',
 array(
        'db'        => 'example_database', 
    )

 LiveAPI Perl Module
my $cpliveapi = Cpanel::LiveAPI->new(); # Connect to cPanel - only do this once.
 
# Generate a list of Postgres database users with access to "example_database"
my $list_pgusers = $cpliveapi->api2(
    'Postgres', 'listusersindb',

 cPanel Tag System (deprecated)


Warnings:

  • In cPanel & WHM version 11.30 and later, cPanel tags are deprecated. We strongly recommend that you only use the LiveAPI system to call the cPanel APIs. Examples are only present in order to help developers move from the old cPanel tag system to our LiveAPI.
  • cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
  • For more information, read our Deprecated cPanel Tag Usage documentation.

 Command Line
cpapi2 --user=username Postgres listusersindb db=example_database


Notes:

  • You must URI-encode values.
  • username represents your account-level username.
  • You must run the --user=username command.
  • For more information and additional output options, read our Guide to cPanel API 2 documentation or run the cpapi2 --help command.
  • If you run CloudLinux™, you must use the full path of the cpapi2 command:
