• Postgresql Versions For Macos Mac

1. Consequently it comes with some versions of Mac OS X. Additionally, some 3rd party software will bundle PostgreSQL because it uses it to store and manage its data. It won't always be obvious what the program is. PostgreSQL generally uses little CPU, RAM or disk I/O unless it's actually being used for serious work, so it's fairly safe to ignore it.
2. I have went through their official sites and many other document to know about the installation process and found out these processes, to reinstall the PostgreSQL if another version of PostgreSQL is installed previously and installing PostGIS in Mac OS. Remove previous versions of PostgreSQL brew uninstall -force postgresql.

Release date: 2018-11-08

This release contains a variety of fixes from 11.0. For information about new features in major release 11, see Section E.9.

A dump/restore is not required for those running 11.X.

However, if you use the pg_stat_statements extension, see the changelog entry below about that.

• Ensure proper quoting of transition table names when pg_dump emits CREATE TRIGGER ... REFERENCING commands (Tom Lane)

  This oversight could be exploited by an unprivileged user to gain superuser privileges during the next dump/reload or pg_upgrade run. (CVE-2018-16850)

• Apply the tablespace specified for a partitioned index when creating a child index (Álvaro Herrera)

  Previously, child indexes were always created in the default tablespace.

• Fix NULL handling in parallel hashed multi-batch left joins (Andrew Gierth, Thomas Munro)

  Outer-relation rows with null values of the hash key were omitted from the join result.

• Fix incorrect processing of an array-type coercion expression appearing within a CASE clause that has a constant test expression (Tom Lane)

• Fix incorrect expansion of tuples lacking recently-added columns (Andrew Dunstan, Amit Langote)

  This is known to lead to crashes in triggers on tables with recently-added columns, and could have other symptoms as well.

• Fix bugs with named or defaulted arguments in CALL argument lists (Tom Lane, Pavel Stehule)

• Fix strictness check for strict aggregates with ORDER BY columns (Andrew Gierth, Andres Freund)

  The strictness logic incorrectly ignored rows for which the ORDER BY value(s) were null.

• Disable recheck_on_update optimization (Tom Lane)

  This new-in-v11 feature turns out not to have been ready for prime time. Disable it until something can be done about it.

• Prevent creation of a partition in a trigger attached to its parent table (Amit Langote)

  Ideally we'd allow that, but for the moment it has to be blocked to avoid crashes.

• Fix problems with applying ON COMMIT DELETE ROWS to a partitioned temporary table (Amit Langote)

• Fix character-class checks to not fail on Windows for Unicode characters above U+FFFF (Tom Lane, Kenji Uno)

  This bug affected full-text-search operations, as well as contrib/ltree and contrib/pg_trgm.

• Ensure that the server will process already-received NOTIFY and SIGTERM interrupts before waiting for client input (Jeff Janes, Tom Lane)

• Fix memory leak in repeated SP-GiST index scans (Tom Lane)

  This is only known to amount to anything significant in cases where an exclusion constraint using SP-GiST receives many new index entries in a single command.

• Prevent starting the server with wal_level set to too low a value to support an existing replication slot (Andres Freund)

• Fix psql, as well as documentation examples, to call PQconsumeInput() before each PQnotifies() call (Tom Lane)

  This fixes cases in which psql would not report receipt of a NOTIFY message until after the next command.

• Fix pg_verify_checksums's determination of which files to check the checksums of (Michael Paquier)

  In some cases it complained about files that are not expected to have checksums.

• In contrib/pg_stat_statements, disallow the pg_read_all_stats role from executing pg_stat_statements_reset() (Haribabu Kommi)

  pg_read_all_stats is only meant to grant permission to read statistics, not to change them, so this grant was incorrect.

  To cause this change to take effect, run ALTER EXTENSION pg_stat_statements UPDATE in each database where pg_stat_statements has been installed. (A database freshly created in 11.0 should not need this, but a database upgraded from a previous release probably still contains the old version of pg_stat_statements. The UPDATE command is harmless if the module was already updated.)

• Rename red-black tree support functions to use rbt prefix not rb prefix (Tom Lane)

  This avoids name collisions with Ruby functions, which broke PL/Ruby. It's hoped that there are no other affected extensions.

• Fix build problems on macOS 10.14 (Mojave) (Tom Lane)

  Adjust configure to add an -isysroot switch to CPPFLAGS; without this, PL/Perl and PL/Tcl fail to configure or build on macOS 10.14. The specific sysroot used can be overridden at configure time or build time by setting the PG_SYSROOT variable in the arguments of configure or make.

  It is now recommended that Perl-related extensions write $(perl_includespec) rather than -I$(perl_archlibexp)/CORE in their compiler flags. The latter continues to work on most platforms, but not recent macOS.

  Also, it should no longer be necessary to specify --with-tclconfig manually to get PL/Tcl to build on recent macOS releases.

• Fix MSVC build and regression-test scripts to work on recent Perl versions (Andrew Dunstan)

  Perl no longer includes the current directory in its search path by default; work around that.

• On Windows, allow the regression tests to be run by an Administrator account (Andrew Dunstan)

  To do this safely, pg_regress now gives up any such privileges at startup.

• Update time zone data files to tzdata release 2018g for DST law changes in Chile, Fiji, Morocco, and Russia (Volgograd), plus historical corrections for China, Hawaii, Japan, Macau, and North Korea.

This is a tutorial for setting up PostgreSQL on MacOS. You might be wondering why there's a need for another setup guide for Postgres in the first place, since there are a few across the web. I found many tutorials and guides on how to set it up, but found most of them to be unclear and outdated, based on old PostgreSQL versions. The checklist is not comprehensive, though, as it is used for several tutorials on my website, I keep it updated with the recent versions of PostgreSQL. If you spot any flaws in this guide, a comment below would be very helpful to keep it up to date for other developers.

If you want to run PostgreSQL on Windows instead, you will find guidance over here: How to setup PostgreSQL on Windows.

PostgreSQL Installation on MacOS

I recommend Homebrew for installing and managing applications on MacOS. It is installed using the following command in the MacOS terminal:

The terminal runs through a series of installation operations, and will probably create folders in your local machine to accommodate Homebrews storage requirements. You can find more detailed instructions here. After it's installed, update the Homebrew dependencies and install PostgreSQL on the command line:

Next, check your PostgreSQL version:

The command line results will show the version you have installed on your local machine. I recommed using the latest version of libraries and software whenever possible to avoid compatibility issues with client-side applications.

How to create a physical PostgreSQL Database

Now you can initialize the physical space on your hard-disk to allocate databases. To do this, create a default postgres database on the command line in case it didn't happen automatically:

You will see the error message: 'initdb: directory '/usr/local/var/postgres' exists but is not empty' if the database was already created when you installed PostgreSQL. It means the folder where you are attempting to create a physical place for the database already has one. Either way, next you can move on to the next step.

When you connect to this physical database later, you will see an actual database which is called 'postgres' as well. The postgres database is meant to be the default database for any third-party tools that you are using in combination with PostgreSQL. These tools attempt to make the default connection to this default database, so you shouldn't delete it.

How to start/stop a PostgreSQL Database

Let's see next how you can interact with the actual database. Manually start and stop your Postgres database server with the following commands:

The terminal will confirm these operations with 'server started' and 'server stopped' feedback. You could also implement a script to start the server each time you boot up the machine, but I like to have control over when to start and stop my database server to avoid complications.

How to create the actual PostgreSQL Database

Next, let's go through the steps of setting up a database that can be used for one of your applications. Make sure the Postgre server is started first, then type these commands in the command line to create and remove a database:

You can also connect to databases to execute SQL statements. Either use the psql command, or specify a database such as the default postgres database to connect:

The command leads you to the psql shell, which you can exit by typing CTRL + d. In the psql shell, you can create and drop databases as well:

To list all your databases, you can type list. Your will see any new databases listed, as well as two default databases that come with postgreSQL called template0 and template1. The templates should remain in your database list even if you aren't using them, as they may be useful later.

• list - List all of your actual databases.
• c mydatabasename - Connect to another database.
• d - List the relations of your currently connected database.
• d mytablename - Shows information for a specific table.
