The docker run command accepts several options and flags that override image and Docker runtime defaults. Running this command creates a new Docker container based on the official postgres Docker image. To get started, let's use Docker to spin up a new PostgreSQL database on the local machine.

deno-postgres provides abstractions for features and operations that allow you to unleash the full potential of PostgreSQL: connection pools, prepared statements, transactions and typed queries.Įxecute queries securely with prepared statements. The API and underlying implementation of deno-postgres is based on two popular PostgreSQL drivers: node-postgres (coincidentally) and pq, a Go PostgreSQL driver.

If you visit the deno.land/x website and search postgres, then you will come across deno-postgres, a lightweight PostgreSQL driver that was developed specifically for Deno. A popular PostgreSQL client for Node.js projects is node-postgres. Since Deno was built as an improved, alternative V8 runtime to Node.js, Deno projects can use both the third-party modules developed specifically to work with Deno and the many third-party packages that exist in the npm ecosystem. Natively support web standard APIs (e.g., fetch).Ĭan process large volumes of data with ACID compliant, concurrent transactions and extensions like PostGIS. Treat TypeScript as a first-class language. You must pass certain security flags to Deno to explicitly grant permissions like network access ( -allow-net). When you bring together two modern, open-source technologies, Deno and PostgreSQL, you can build production-grade web applications that. More than one of these libraries might be available on a particular machine, so configure does not automatically choose one.Most modern web applications rely on a relational database management system (RDBMS) to store and retrieve troves of related data. When invoking configure, specify -with-uuid=bsd to use the BSD functions, or -with-uuid=e2fs to use e2fsprogs' libuuid, or -with-uuid=ossp to use the OSSP UUID library. On Linux, OS X, and some other platforms, suitable functions are provided in the libuuid library, which originally came from the e2fsprogs project (though on modern Linux it is considered part of util-linux-ng). On FreeBSD, NetBSD, and some other BSD-derived platforms, suitable UUID creation functions are included in the core libc library. uuid-ossp can now be built without the OSSP library on some platforms. While the OSSP UUID library can still be found at, it is not well maintained, and is becoming increasingly difficult to port to newer platforms. Historically this module depended on the OSSP UUID library, which accounts for the module's name. Version 5 should be preferred over version 3 because SHA-1 is thought to be more secure than MD5. This function generates a version 5 UUID, which works like a version 3 UUID except that SHA-1 is used as a hashing method.
Uuid_generate_v5(namespace uuid, name text) This function generates a version 4 UUID, which is derived entirely from random numbers. The generation of UUIDs by this method has no random or environment-dependent element and is therefore reproducible. The name parameter will be MD5-hashed, so the cleartext cannot be derived from the generated UUID. (It could be any UUID in theory.) The name is an identifier in the selected namespace.įor example: SELECT uuid_generate_v3(uuid_ns_url(), '') The namespace should be one of the special constants produced by the uuid_ns_*() functions shown in Table F-34. This function generates a version 3 UUID in the given namespace using the specified input name. Uuid_generate_v3(namespace uuid, name text)

This function generates a version 1 UUID but uses a random multicast MAC address instead of the real MAC address of the computer. Note that UUIDs of this kind reveal the identity of the computer that created the identifier and the time at which it did so, which might make it unsuitable for certain security-sensitive applications. This involves the MAC address of the computer and a time stamp. This function generates a version 1 UUID.
