Regex for Word space Word space Word ....
I tried nested regex '[[A-Z][a-z] ]+[[A-Z][a-z]]' but it did not work.

[A-Z][a-z]+ +[A-Z][a-z]+
will match 'Hello World', but not 'Hello world'. Is that what you want?
Try this instead
[A-Za-z]+ +[A-Za-z]+
And try also this editor to learn regex

./hans
It only matches First Street from 'My First Street'.
I was trying to make it to match words starting capital letter only.

You'll want to include unicode-characters, which [A-Z] approach doesn't handle
well.
How about:
select regexp_matches('Åge is a Man', E'[[:upper:]]\\w+', 'g');

It isn't very clear what you want to achieve. From the other mails in
this thread I understand that your words start with an uppercase char
and continue with lowercase chars. Is that right?
You want exactly one space between words, or more than one?
What is this "...and more"? Arbitrary repetitions?
Which kind of regular expressions do you want to use? POSIX?
If all the answers to the above are "yes", you might try something like
"(?:[[:upper:]][[:lower:]]*[[:space:]]+)*[[:upper:]][[:lower:]]*"
(Caveat: untested). This would match a single word or more than one
word, separated by one or more spaces, where a word starts with one
upper-case character and continues with zero or more lowercases.

What problem are you actually trying to solve? You may find it easier to
simply split your string on space and then do tests on elements of the
resultant array.

Hi, David J,
Any good example of doing test on array?
