Answer Source

If your case is that simple: exactly one / in the string, use split_part():

SELECT split_part(source_path, '/', 2) FROM movies_history;

If there can be multiple /, and you want the string after the last one, use substring() with a regular expression:

SELECT substring(source_path, '[^/]*$') FROM movies_history;


[...] .. encloses a list of characters to form a character class.
[^...] .. if the list starts with ^ it's the inversion (all characters not in the list).
* .. quantifier for 0-n times.
$ .. anchor to end of string.
