Installing VectorChord

Suggest edits

VectorChord packages are available via the EDB repositories. The extension uses the pgvector's vector data type and adds the VectorChord's index access method (vchordq).

Prerequisites

Install your flavor of Postgres if not already installed. See:
Set up the repository:
Setting up the repository is a one-time task. If you've already set up your repository, you don't need to perform this step.
To set up the repository, go to EDB repositories and follow the instructions provided there.
Install pgvector (for the vector data type) and the VectorChord packages.
For SLES, CentOS, RHEL and its derivatives:
```
sudo <package-manager> -y install edb-<postgres><postgres_version>-pgvector0
```
For Debian and Ubuntu:
```
sudo <package-manager> -y install edb-<postgres><postgres_version>-pgvector-0
```

<package-manager> is the package manager used with your operating system:
Package manager Operating system
dnf RHEL 8/9 and derivatives
zypper SLES
apt-get Debian and derivatives
<postgres> is the distribution of Postgres you're using:
Postgres distribution Value
PostgreSQL pg
EDB Postgres Advanced Server as
EDB Postgres Extended Server postgresextended
<postgres_version> is the version of Postgres you're using.

dnf	RHEL 8/9 and derivatives

For example, to install pgvector for EDB Postgres Advanced Server 15 on a RHEL 8 platform:

sudo dnf -y install edb-as15-pgvector0

Install the package

sudo <package-manager> -y install edb-<postgres><postgres_version>-vectorchord
