In this post, I am providing a solution to split a string by using a different type of delimiters in PostgreSQL.
Splitting a string is a very common requirement for all PostgreSQL Database Developers.
I used regexp_split_to_array to split the string and store the result into a string array. You can pass any delimiters.

Below are two sample example using regexp_split_to_array():

SELECT 
	a[1] AS DiskInfo
	,a[2] AS DiskNumber
	,a[3] AS MessageKeyword
FROM (
    SELECT regexp_split_to_array('Postgres Disk information : disk 2 : failed', ':')
) AS dt(a)


SELECT 
	a[1] AS DiskInfo
	,a[2] AS DiskNumber
	,a[3] AS MessageKeyword
FROM (
    SELECT regexp_split_to_array('Postgres Disk information , disk 2 , failed', ',')
) AS dt(a)

The result:
