pg_config paths¶

pg_config is the small utility that reports where a PostgreSQL installation keeps its files — the make install commands throughout this site need its path so they know where to place pg_relay's files.

Platform	pg_config path
RHEL / Rocky / AlmaLinux 8/9	`/usr/pgsql-{version}/bin/pg_config`
Ubuntu 24.04 / Debian 12	`/usr/lib/postgresql/{version}/bin/pg_config`
macOS Homebrew (Apple Silicon)	`/opt/homebrew/opt/postgresql@{version}/bin/pg_config`
macOS Homebrew (Intel)	`/usr/local/opt/postgresql@{version}/bin/pg_config`

Go version¶

Go 1.26.5 or later is required to build the Processor from source. It has only one external dependency: github.com/jackc/pgx/v5 (a PostgreSQL driver for Go). Everything else it uses comes from the Go standard library.

Windows notes¶

There is no make on Windows. Use the PowerShell installer instead:

# Run as Administrator:
.\deploy\install-extension.ps1 -PgVersion 18

This copies pg_relay.control and every SQL script needed to reach the current version to the correct share\extension\ directory for the PostgreSQL version you specify.

The Processor binary is installed as a Windows service using NSSM — see Installing the Processor in the User Guide for the full command sequence.
