Postico 1.0.4 – A modern PostgreSQL Client. February 26, 2016 Postico provides an easy to use interface, making Postgres more accessible for newcomers and specialists alike. Postico 1 5 2 – A Modern Postgresql Client Permissions Download PostgreSQL, while being an modern and versatile RDBMS, is not the easiest ofbeasts to setup and get going while you’re looking to develop an application.Read on to learn about how you can get started with the latest version ofPostgreSQL on the LTS version of Ubuntu. After the installation, PostgreSQL 9.1 or below is running under a local account named 'postgres'. 9.2 or above instead install into NETWORKSERVICE by default. If you want to use SSPI securely access a domain, you need to change the service to run under a domain account because SSPI requires that the service uses a domain account. 一応、DBの中身もGUIツールで確認した。良い感じ。 Postico – a modern PostgreSQL client for the Mac.
Postgres.app has a beautiful user interface and a convenient menu bar item.You never need to touch the command line to use it – but of course we do include all the necessary command line tools and header files for advanced users.
Postgres.app can install minor updates automatically, so you get bugfixes as soon as possible.
Installing Postgres.app
- Download ➜ Move to Applications folder ➜ Double ClickXline 2 0 4 – mind mapping application. If you don't move Postgres.app to the Applications folder, you will see a warning about an unidentified developer and won't be able to open it.
- Click 'Initialize' to create a new server
- Configure your $PATH to use the included command line tools (optional):
Done! You now have a PostgreSQL server running on your Mac with these default settings:
Host | localhost |
Port | 5432 |
User | your system user name |
Database | same as user |
Password | none |
Connection URL | postgresql://localhost |
To connect with psql, double click a database. To connect directly from the command line, type
psql
. If you’d rather use a graphical client, see below.NOTE: These instructions assume that you’ve never installed PostgreSQL on your Mac before.If you have previously installed PostgreSQL using homebrew, MacPorts, the EnterpriseDB installer, consider removing other PostgreSQL installations first.We also have instructions for upgrading from older versions of Postgres.app.
Graphical Clients
Postgres.app includes
psql
, a versatile command line client for PostgreSQL.But it’s not the only option; there are plenty of great graphical clients available for PostgreSQL.Two popular tools are:pgAdmin 4 is a feature rich open source PostgreSQL client.It has support for almost every feature in PostgreSQL.The only downside is that the cross-plattform UI really doesn’t live up to the expectations of a native Mac app.
Postico on the other hand, is a very modern Mac app.It’s made by the same people that maintain Postgres.app, and we think you’ll like it! We put a lot of effort into making it a joy to use.However, it doesn’t have the extensive feature set of pgAdmin, and it’s a commercial app rather than open source.
Aside from those two options, there are a lot more to choose from! Check the documentation for a list of amazing Mac apps for PostgreSQL.
How to connect
After your PostgreSQL server is up and running, you’ll probably want to connect to it from your application.Here’s how to connect to PostgreSQL from popular programming languages and frameworks:
To connect from PHP, make sure that it supports PostgreSQL. The version included with macOS doesn't support PostgreSQL. We recommend MAMP for an easy way to install a current version of PHP that works.
You can use PDO (object oriented):
Or the pg_connect() functions (procedural):
To connect to a PostgreSQL server with Python, please first install the psycopg2 library:

Sinatra
In config.ru or your application code:
ActiveRecord
Install the activerecord gem and require 'active_record', and establish a database connection:
DataMapper
Install and require the datamapper and do_postgres gems, and create a database connection:
Sequel
Install and require the sequel gem, and create a database connection:
- Download and install the PostgreSQL JDBC driver
- Connect to the JDBC URL jdbc:postgresql://localhost

libpq is the native C client library for connecting to PostgreSQL. It's really easy to use:
Now compile the file with clang and run it:
You can just use the C API in Swift! First include libpq in your bridging header:
Then make sure to link with libpq. Keep it 1 8 22.
On iOS, you'll need to build libpq yourself.
On macOS you can use the system provided libpq (does not support SSL) or use libpq provided by Postgres.app by adding the following build settings:
Other Linker Flags | -lpq |
---|---|
Header Search Paths | /Applications/Postgres.app/Contents/Versions/latest/include |
Library Search Paths | /Applications/Postgres.app/Contents/Versions/latest/lib |
Now you can use the libpq C library to connect to PostgreSQL:

This article provides comprehensive documentation for Security-Enhanced PostgreSQL (SE-PostgreSQL).SE-PostgreSQL is a built-in enhancement of PostgreSQL, providing additional access controls based on Security-Enhanced Linux (SELinux) security policy. The following chapters show the background, overview, design, and references (object classes, permissions, etc.) for SE-PostgreSQL.

- Introduction
- 1What is SE-PostgreSQL
Databases are significant facilities for managing information assets.Databases enable information to be searched for, retrieved, and stored in more elegant ways than with file systems.
Most existing RDBMSs apply their own access controls, for example, GRANT and REVOKE, without collaborating with operating system. This can result in inconsistent access controls compared to ones on filesystem and so on.
Some modern operating systems have enhanced access control features, such as SELinux.The design of most of these features is based upon the reference monitor model (which came from 1980's researches), that allows all system access to be managed by a centralized security policy.The reference monitor model assumes that object managers (for example, operating systems) can capture all system access, and then make decisions about whether that access is allowed or denied. Note: an operating systems is not the object manager in all cases.A Relational Database Management System (RDBMS) is an object manager for database objects, similar to operating systems being object managers for file system objects. Previously, RDBMSs made access control decisions independently from a centralized security policy, and as such, meticulous care to keep its consistency between OS and RDBMS.
SE-PostgreSQL is a built-in enhancement of PostgreSQL, providing fine-grained mandatory access control (MAC) for database objects.SE-PostgreSQL makes access control decisions based on SELinux security policy, the same way user access to file system objects is managed by the operating system. It provides the following significant features:
Mandatory access controls
PostgreSQL uses the concept of a database superuser that can bypass all access controls of native PostgreSQL. On the contrary, SE-PostgreSQL enforces its access control on any client, without exception, even if the client is a database superuser.Clients can only access database objects when access is allowed by both native PostgreSQL and SE-PostgreSQL, similar to the relationship between Discretionary Access Control (DAC) and Mandatory Access Control (MAC) on certain operating systems.
Fine-grained access controls
Granularity of access control depends on the RDBMS. SE-PostgreSQL allows access control to be configured at the column and row levels (only a few proprietary RDBMSs support column and row level access-control options).
Columns and rows are the smallest unit of database objects. Access control on these objects allows database administrators to apply flexible access control on them.
Consistency in access controls
SELinux requires all processes and objects to have a security context that represents its privileges and attributes. SE-PostgreSQL assigns a security context on each database objects (which are tuples in system/general tables), and makes access control decisions based on the privileges and attributes as if SELinux applies them in the kernel.
libselinux provides an interesting API named as getpeercon(), that enables you to get the security context of a peer process connecting to a server process. SE-PostgreSQL needs security contexts to make its decisions. This is a significant feature for consistency in access controls, in that privileges for clients and the attributes for objects are represented in the same form.
Consider RDBMSs (including PostgreSQL) as an inter-process communication channel, the same as file systems, networks, IPC, and so on.
The most significant purpose for security mechanisms is to protect classified information being leaked. On subsystems with individual access controls -- not a centralized one -- an attacker can choose the weakest inter-process communication channel.
SELinux is an operating system feature that applies a single, unified security policy over the whole operating system. System calls are intercepted and inspected. This approach allows policy to be enforced with minimal costs; however, keep in mind that several user-space object managers, such as the X Window System and RDBMSs, can be used as inter-process communication channels. Resources managed in user-space are invisible to the kernel, leaving two options for security policy: the traditional all-or-nothing policy, that does not allow user-space objects to be shared (this is unrealistic), or the enhancement of user-space object managers, making their access control decisions based on the single, unified security policy of SELinux.
The above figure demonstrates consistent
