Installing VectorChord

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

Prerequisites

• Supported Postgres (EPAS or PostgreSQL) per the EDB compatibility matrix
• EDB repositories configured on the host
• pgvector installed for the vector data type

Install steps

1) Install Postgres and configure the EDB repositories. 2) Install pgvector (provides the vector type). 3) Install the VectorChord package (provides the vchordq index access method).

Packaging and provenance

• EDB builds, signs, and publishes packages across supported platforms.
• Each package build records the upstream source it was built from. To view it, check the package changelog or metadata:
  • RPM‑based: rpm -q --changelog <package> or dnf info <package>
  • Debian/Ubuntu: apt changelog <package> or apt show <package>
• Verify repository signatures using the EDB GPG key installed during repository setup.
