Write a PostgreSQL script that contains the following elements.

1) A table ALBUMS of your own, as well as a word index table that contains album id and individual words in a title. Be careful not to forget the necessary constraints.

2) A function that sanitizes a title, removing punctuation and turning everything to the same case (your choice: upper or lower). Youll probably want to use the translate() PostgreSQL function in your solution, and the following list for punctuation: #@&"''(!)-_$*%<>[{]},?;.:/=+

3) A function that takes two parameters, an album id and a title, and populates the index table containing album id and words (after sanitizing the title). Your function will ignore one-letter words.
