Consider the following 2-D ARRAY data type and table.

CREATE TYPE shot_ary AS INTEGER ARRAY[1:50][1:50];
CREATE TABLE seismic_data (
   id INTEGER,
   shot1 shot_ary,
   shot2 shot_ary);

The following query returns an element value, which is the minimum of all the element values in the shot1 array.

SELECT ARRAY_MIN(shot1) FROM seismic_data;

The following query returns an element value, which is the minimum of the element values within the specified scope of the shot1 array.

SELECT ARRAY_MIN(shot1, NEW arrayVec(5,5), NEW arrayVec(10,10)) 
FROM seismic_data;

The following is the same query using method-style syntax.

SELECT shot1.ARRAY_MIN(NEW arrayVec(5,5), NEW arrayVec(10,10)) 
FROM seismic_data;
