Build

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

pig build pkg pg_hashids         # build RPM / DEB packages

Install

You can install pg_hashids 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 pg_hashids;          # Install for current active PG version

pig

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

dnf

dnf install -y pg_hashids_18       # PG 18
dnf install -y pg_hashids_17       # PG 17
dnf install -y pg_hashids_16       # PG 16
dnf install -y pg_hashids_15       # PG 15
dnf install -y pg_hashids_14       # PG 14

apt

apt install -y postgresql-18-pg-hashids   # PG 18
apt install -y postgresql-17-pg-hashids   # PG 17
apt install -y postgresql-16-pg-hashids   # PG 16
apt install -y postgresql-15-pg-hashids   # PG 15
apt install -y postgresql-14-pg-hashids   # PG 14

Create Extension:

CREATE EXTENSION pg_hashids;

Usage

pg_hashids: generate short unique ids from integers

Converts numbers like 347 into strings like “yr8”. Useful for obfuscating database primary keys.

CREATE EXTENSION pg_hashids;

Functions

Function	Description
`id_encode(number [, salt [, min_length [, alphabet]]])`	Encode an integer to a hashid string
`id_decode(hash, salt, min_length [, alphabet])`	Decode a hashid string back to integer array
`id_decode_once(hash [, salt [, min_length [, alphabet]]])`	Decode a hashid string back to a single integer

Examples

-- Basic encoding
SELECT id_encode(1001);                                    -- 'jNl'
SELECT id_encode(1234567, 'This is my salt');              -- 'Pdzxp'
SELECT id_encode(1234567, 'This is my salt', 10);          -- 'PlRPdzxpR7'

-- Custom alphabet
SELECT id_encode(1234567, 'This is my salt', 10, 'abcdefghijABCDxFGHIJ1234567890');
-- '3GJ956J9B9'

-- Decoding (use the same salt!)
SELECT id_decode('PlRPdzxpR7', 'This is my salt', 10);     -- 1234567
SELECT id_decode_once('jNl');                               -- 1001
SELECT id_decode_once('Pdzxp', 'This is my salt');          -- 1234567
