Hi, Adrian Klaver,
In Python, there is a capwords. Do we have an equivalent in Postgres?
https://docs.python.org/3/library/string.html?highlight=capwords#string.capwords
string.capwords(s, sep=None)
Split the argument into words using str.split(), capitalize each
word using str.capitalize(), and join the capitalized words using
str.join(). If the optional second argument sep is absent or None, runs
of whitespace characters are replaced by a single space and leading and
trailing whitespace are removed, otherwise sep is used to split and join
the words.
That is not going to do what you are proposing either as it still comes
down to deciding where to split the 'words':
import string
string.capwords('notemachine')
'Notemachine'
There are similar functions to split strings here:
https://www.postgresql.org/docs/14/functions-string.html
Though again they depend on some delimiter or regexp to make the split.
There is no function that just 'knows' that 'notemachine' is two words
and should become 'NoteMachine'.
