Installation Instructions for pglogical
pglogical is available as RPMs via yum for Fedora, CentOS, & RHEL, and as DEBs via apt for Debian and Ubuntu, or as source code . Please see below for instructions on installing from source.
YUM Repository for pglogical
The instructions below are valid for Red Hat family of operating systems (RHEL, CentOS, Fedora).
These RPMs all require the PGDG PostgreSQL releases from If you don't have PostgreSQL already:. You cannot use them with stock PostgreSQL releases included in Fedora and RHEL.
- Install the appropriate PGDG repo rpm from
- Install PostgreSQL
- v9.4: yum install postgresql94-server postgresql94-contrib
- v9.5: yum install postgresql95-server postgresql95-contrib
- v9.6: yum install postgresql96-server postgresql96-contrib
Next step is to install the matching pglogical version. In order to do that, you should first install the repository RPM for your distro.
- Fedora 24 and 25: yum install http://packages.2ndquadrant.com/pglogical/yum-repo-rpms/pglogical-fedora-1.0-2.noarch.rpm
- RHEL/CentOS 6 and 7: yum install http://packages.2ndquadrant.com/pglogical/yum-repo-rpms/pglogical-rhel-1.0-2.noarch.rpm
Once the repository is installed, you can proceed to pglogical for your PostgreSQL version:
- PostgreSQL 9.4: yum install postgresql94-pglogical
- PostgreSQL 9.5: yum install postgresql95-pglogical
- PostgreSQL 9.6: yum install postgresql96-pglogical
You may be prompted to accept the repository GPG key for package signing:
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-2NDQ-PGLOGICAL Importing GPG key 0xEB74CAFE: Userid : "pglogical repository key (2ndQuadrant) <[email protected]>" Fingerprint: 0005 a7af 6208 3d86 d273 d5cb bc66 be8f eb74 cafe Package : pglogical-fedora-1.0-1.noarch (installed) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-2NDQ-PGLOGICAL Is this ok [y/N]:
If so, accept the key (if it matches the above) by pressing 'y' then enter. (It's signed by the 2ndQuadrant master packaging key, if you want to verify that.)
APT Repository for pglogical
The instructions below are valid for Debian and all Linux flavors based on Debian (e.g. Ubuntu).
In order to use 2ndQuadrant's repository, first perform the following steps:
- Create file /etc/apt/sources.list.d/2ndquadrant.list. The distributions are called codename-2ndquadrant.
- In the command below, replace "jessie" with the actual distribution you are using. (You may determine the codename of your distribution by running lsb_release -c.)
deb [arch=amd64] http://packages.2ndquadrant.com/pglogical/apt/ jessie-2ndquadrant main
- Add the repository. See the site for instructions.
- Import the 2ndQuadrant apt repository key, update the package lists, and start installing packages
wget --quiet -O - http://packages.2ndquadrant.com/pglogical/apt/AA7A6805.asc | sudo apt-key add - sudo apt-get update
Once pre-requisites are complete, installing pglogical is simply a matter of executing the following for your version of PostgreSQL:
- PostgreSQL 9.4: sudo apt-get install postgresql-9.4-pglogical
- PostgreSQL 9.5: sudo apt-get install postgresql-9.5-pglogical
- PostgreSQL 9.6: sudo apt-get install postgresql-9.6-pglogical
Installing pglogical from Source Code
Source code installs are the same as for any other PostgreSQL extension built using PGXS.
Make sure the directory containing
pg_config from the PostgreSQL release is listed in your
PATH environment variable. You might have to install a
-devel package for your PostgreSQL release from your package manager if you don't have
make USE_PGXS=1 to compile, and
make USE_PGXS=1 install to install. You might need to use
sudo for the install step.
e.g. for a typical Fedora or RHEL 7 install, assuming you're using the yum.postgresql.org packages for PostgreSQL:
sudo dnf install postgresql96-devel PATH=/usr/pgsql-9.6/bin:$PATH make USE_PGXS=1 clean all sudo PATH=/usr/pgsql-9.6/bin:$PATH make USE_PGXS=1 install
Note that you must install pglogical on all servers that will act as publishers or subscribers. So if you're replicating from 9.4 to 9.5 you'd install postgresql94-pglogical on the 9.4 server and postgresql95-pglogical on the 9.5 server. You cannot install just the pglogical-output plugin.
