## Description:
|
||||
|
||||
`pg` is a wrapper for the PostgreSQL client library. It provides access to a PostgreSQL
|
||||
database server.
|
||||
|
||||
Before you can use this module, you must first have PostgreSQL installed on your system.
|
||||
To do this, find your OS and perform the actions listed.
|
||||
|
||||
**NOTE**: These instructions are meant only as a convenience. If your OS is not listed
|
||||
or you need extra help, [go here](https://www.postgresql.org/download/).
|
||||
|
||||
### Fedora 31
|
||||
```
|
||||
sudo dnf install postgresql-server postgresql-contrib
|
||||
sudo systemctl enable postgresql # to autostart on startup
|
||||
sudo systemctl start postgresql
|
||||
```
|
||||
|
||||
### Ubuntu/Debian
|
||||
```
|
||||
sudo apt-get install postgresql postgresql-client
|
||||
sudo systemctl enable postgresql # to autostart on startup
|
||||
sudo systemctl start postgresql
|
||||
```
|
||||
|
||||
### MacOSX (Homebrew)
|
||||
```
|
||||
brew install postgresql
|
||||
brew services start postgresql
|
||||
```
|
||||
|
||||
### MacOSX (MacPorts)
|
||||
```
|
||||
gem install pg -- --with-pg-config=/opt/local/lib/postgresql[version number]/bin/pg_config
|
||||
```
|
||||
|
||||
## Installing libpq-dev or its equivalent for your OS: ##
|
||||
|
||||
**Ubuntu/Debian**: `sudo apt-get install libpq-dev`
|
||||
|
||||
**Red Hat Linux (RHEL)**: `yum install postgresql-devel`
|
||||
|
||||
**OpenSuse**: `zypper in postgresql-devel`
|
||||
|
||||
**ArchLinux**: `pacman -S postgresql-libs`
