These instructions are for PostgreSQL 9.1 and higher, PostGIS 2.2 and higher that is compiled with raster support.Note: if you have postgis, without raster support, you can not use CREATE EXTENSION. Refer to PostGIS install.
1 day ago It is with postgres on my mac. I set a password for postgres and I can not remember it for some reason. I have looked up and attempted several different methods for trying to reset the password but none of them are working and I need it fixed as soon as possible. PostgreSQL is a robust, scalable and well supported Open Source database engine. This packaging installs it into Mac OS sensitive locations and adds some limited graphical management tools, with.

Enabling PostGIS
Hi I am having trouble with postgres. I don't remember my postgres password and don't know how to change the password. I'm guessing I should change the md5 password settings I set a month ago, but I don't know how to find the file and open it using my terminal.
PostGIS is an optional extension that must be enabled in each database you want to use it in before you can use it. Installing the software is just the first step.DO NOT INSTALL it in the database called
postgres
.Connect to your database with
psql
or PgAdmin. Run the following SQL.You need only install the features you want:Upgrading PostGIS
To upgrade PostGIS, you first have to install the latest binaries and then upgrade each database you have PostGIS installed in
For example connect to database you want to upgrade and if you just installed binaries for 2.1.3You can upgrade from 2.0 to 2.1, 2.2 et.c using this approach. To go from 1.* to 2.* you need to do a hard upgrade.Refer to PostGIS install for more extensive instructions.Note: that as of PostGIS 2.1.3 and PostGIS 2.0.6, you need to set environment variables to get full features.

How To Install Postgresql On Mac
I started off programming Ruby on Rails applications on a Windows machine with an Ubuntu virtual machine running on top. But when I got my first job at a startup in California, I received a brand new shiny Macbook laptop.
I had never used a Mac before as I considered them overpriced relative to a desktop I could setup with Linux. But since that’s what I was given, that’s what I was used. One of the first things I had to do is figure out how to get Postgres up and running.
Eventually, I had to learn a good way to upgrade it as well. At my first job, I found that using Heroku’s Postgres app. At my next job, I used the homebrew package manager since that’s how our team used it.
So what follows is a mini-guide I put together on how to install postgresql on Mac as well as how to upgrade it with homebrew.
Now if you want to use Heroku’s Postgres app, it’s pretty easy and is a good alternative to homebrew. Project professional 2013 for mac.
Installing Postgres via Homebrew
This guide assumes that you have homebrew installed. If you don’t, you can find some instructions here.
Once you do that, all you have to do is issue the following command in your terminal:
$ brew install postgres
It should install the latest version of Postgres available via Homebrew. Pretty easy, right?
Upgrading Postgres via Homebrew
Ok, so let’s say you have to upgrade postgres. I had to follow these steps when I was upgrading to Postgres 9.6
Step 1 – Turn off Postgres
The first step is to turn off the postgres service if it’s running in the background.
$ brew services stop postgresql
Step 2 – Upgrade
Next, we’ll use homebrew to upgrade it to the latest version.
$ brew update && brew upgrade postgresql
Step 3 – Switch
Finally, we’ll switch to the new version using the following command.
brew switch 9.6.1
You’ll see output like the following:
Step 4 – Ensuring Postgresql Starts Automatically At Startup (optional, but makes your life easier)
Now to ensure postgres starts automatically every time you start your Mac, you’ll need to do some extra setup.
I got the following setup from this blog post at tunnelsup.
Step A – You’ll need to setup LaunchAgents
Create the directory ~/Library/LaunchAgents if it doesn’t exist already.
Step B – Copy the plist file to ~/Library/LaunchAgents/
There’s a plist file that comes with the postgres install from homebrew.
When upgrading to 9.6.2, my plist was at /usr/local/Cellar/postgresql/9.6.2/homebrew.mxcl.postgresql.plist.
Copy the plist file to the LaunchAgents directory.
cp /usr/local/Cellar/postgresql/9.3.4/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
Step C – Load launchctl
Now use launchctl to load the file using this command:
$ launchctl load -w homebrew.mxcl.postgresql.plist
You can also use a ruby gem called lunchy. I haven’t tried it but this blog post describes the process.
General Troubleshooting Tips And Useful Commands
The following command will show you if you have multiple versions of postgres installed.
$ brew info postgresql
This troubleshooting gist describes how to migrate data from one version of Postgres to another.
Troubleshooting Guide for Rails developers
This part gives you some common troubleshooting tips if you’re a Rails developer.
Since I primarily use Postgres for Ruby on Rails work, when I was upgrading I had a connection issue described below.
Postgresql For Mac
If you get a connection issue with a message such as the following:
Then try running this in your terminal:
If you see the above “FATAL…”, then issue the following commands:
WARNING: Before you issue the following commands, please make sure you back up your old local Postgres data if you need it. See the gist referenced in the General Troubleshooting Tips And Useful Commands section.
$ rm -rf /usr/local/var/postgres && initdb /usr/local/var/postgres -E utf8
Postgres Command For Mac
After running the above rm and initdb commands, you should see something similar to the following.
Summary
Postgresql For Mac
If you want to install Postgres via homebrew, follow the steps above. Make sure you backup your local data if you need it so you don’t accidentally erase something you need to keep. Other than that, let me know if you have any issues in the comments.
