Build

You can build the RPM / DEB packages for pgqr using pig build:

pig build pkg pgqr         # build RPM / DEB packages

Install

You can install pgqr directly. First, make sure the PGDG and PIGSTY repositories are added and enabled:

pig repo add pgsql -u          # Add repo and update cache

Install the extension using pig or apt/yum/dnf:

Install

pig install pgqr;          # Install for current active PG version

pig

pig ext install -y pgqr -v 18  # PG 18
pig ext install -y pgqr -v 17  # PG 17
pig ext install -y pgqr -v 16  # PG 16
pig ext install -y pgqr -v 15  # PG 15
pig ext install -y pgqr -v 14  # PG 14

dnf

dnf install -y pgqr_18       # PG 18
dnf install -y pgqr_17       # PG 17
dnf install -y pgqr_16       # PG 16
dnf install -y pgqr_15       # PG 15
dnf install -y pgqr_14       # PG 14

apt

apt install -y postgresql-18-pgqr   # PG 18
apt install -y postgresql-17-pgqr   # PG 17

apt install -y postgresql-15-pgqr   # PG 15
apt install -y postgresql-14-pgqr   # PG 14

Create Extension:

CREATE EXTENSION pgqr;

Usage

pgqr: QR code generation for PostgreSQL

Function

pgqr(t text, correction_level integer, model_number integer, scale integer) RETURNS bytea

Parameters:

t – text to encode into the QR code
correction_level – error correction level: 0 to 3
model_number – QR model number: 0 to 2
scale – pixels per dot (scaling factor)

Example

Generate a QR code as a monochrome bitmap:

SELECT pgqr('QR Code with PostgreSQL', 0, 0, 4);

The output is a monochrome bitmap image (BMP format) returned as bytea, ready for display or storage.
