Create Extension:

CREATE EXTENSION pg_geohash;

Usage

pg_geohash: Geohash functions for PostgreSQL

C-based geohash functions for PostgreSQL (also supports HAWQ and Greenplum). Based on the libgeohash C library.

Background on geohash: Wikipedia: Geohash

Functions

Encode latitude/longitude to a geohash string with specified precision:

SELECT LAT_LON_TO_GEOHASH_WITH_LEN(latitude, longitude, 5) AS geohash;

Encode latitude/longitude to a full-precision geohash:

SELECT LAT_LON_TO_GEOHASH(latitude, longitude) AS geohash;

Decode a geohash back to latitude/longitude:

SELECT GEOHASH_TO_LAT_LON('dp3w7') AS lat_lon;

Example

Compute geohash-based aggregates using 5-character precision (~2.4km x 4.9km cells):

SELECT LAT_LON_TO_GEOHASH_WITH_LEN(latitude, longitude, 5) AS geohash,
       COUNT(*)
FROM crimes
GROUP BY 1
ORDER BY 2 DESC
LIMIT 10;

 geohash | count
---------+-------
 dp3w7   | 72404
 dp3tt   | 70713
 dp3tw   | 63642
 dp3wm   | 62332
 dp3wk   | 56467

Recover coordinates from a geohash:

SELECT location,
       GEOHASH_TO_LAT_LON(LAT_LON_TO_GEOHASH(latitude, longitude))
FROM crimes
LIMIT 5;
