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 here. 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). 

Pre-Requisites

These RPMs all require the PGDG PostgreSQL releases from http://yum.postgresql.org/. You cannot use them with stock PostgreSQL releases included in Fedora and RHEL. If you don't have PostgreSQL already:

  • Install the appropriate PGDG repo rpm from http://yum.postgresql.org/repopackages.php
  • 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
    • v10: yum install postgresql10-server postgresql10-contrib
    • v11: yum install postgresql11-server postgresql11-contrib

Installing pglogical

You can install the "2ndQuadrant's General Public" repository for your PostgreSQL version, by running the following instructions as root on the destination Linux server:

curl https://access.2ndquadrant.<wbr/>com/api/repository/dl/default/<wbr/>release/9.4/rpm | bash
curl https://access.2ndquadrant.<wbr/>com/api/repository/dl/default/<wbr/>release/9.5/rpm | bash
curl https://access.2ndquadrant.<wbr/>com/api/repository/dl/default/<wbr/>release/9.6/rpm | bash
curl https://access.2ndquadrant.<wbr/>com/api/repository/dl/default/<wbr/>release/10/rpm | bash
curl https://access.2ndquadrant.<wbr/>com/api/repository/dl/default/<wbr/>release/11/rpm | bash

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
  • PostgreSQL 10: yum install postgresql10-pglogical
  • PostgreSQL 11: yum install postgresql11-pglogical

Package Signing

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-DL-DEFAULT
Importing GPG key 0xD6BAF0C3:
 Userid     : "Public repository signing key 2ndQuadrant <[email protected]>"
 Fingerprint: 8565 305c ea7d 0b66 4933 d250 9904 cd4b d6ba f0c3
 From       : /etc/pki/rpm-gpg/RPM-GPG-KEY-2NDQ-DL-DEFAULT
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). 

Pre-Requisites

You can install the "2ndQuadrant's General Public" repository by running the following instructions as root on the destination Linux server:

curl https://access.2ndquadrant.<wbr/>com/api/repository/dl/default/<wbr/>release/deb | bash

Installing pglogical

You can install the "2ndQuadrant's General Public" repository for your PostgreSQL version, by running the following instructions as root on the destination Linux server:

curl https://access.2ndquadrant.com/api/repository/dl/default/release/9.4/rpm | bash

curl https://access.2ndquadrant.com/api/repository/dl/default/release/9.5/rpm | bash

curl https://access.2ndquadrant.com/api/repository/dl/default/release/9.6/rpm | bash

curl https://access.2ndquadrant.com/api/repository/dl/default/release/10/rpm | bash

curl https://access.2ndquadrant.com/api/repository/dl/default/release/11/rpm | bash

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
  • PostgreSQL 10: sudo apt-get install postgresql-10-pglogical
  • PostgreSQL 11: sudo apt-get install postgresql-11-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 -dev or -devel package for your PostgreSQL release from your package manager if you don't havepg_config.

Then run 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

Important

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.

For more information, please read the pglogical README.md in /usr/share/doc/postgresql<version>-pglogical/README.md where <version> would be 94,95,96,10
