>Summary: SQL: incomplete documentation

Initial Comment:
On the website, the following string operations are shown:

string_funcs:
        SUBSTRING ( scalar_exp FROM scalar_exp FOR scalar_exp )
      | SUBSTRING ( scalar_exp, scalar_exp, scalar_exp )
      | SUBSTRING ( scalar_exp FROM scalar_exp )
      | SUBSTRING ( scalar_exp, scalar_exp )
      | SUBSTRING ( scalar_exp <int_value> scalar_exp )
      | scalar_exp CONCATSTRING scalar_exp

However, 
   scalar_exp CONCATSTRING scalar_exp
doesn't appear to be valid.
Instead, 
   concat(scalar_exp, scalar_exp)
seems to d the job.

Message:
After talking to Fabian, I learned that CONCATSTRING is defined as ||.

But how am I (as a user) supposed to know that? 

So, the real problem of this bug report is that documentation on web is
not incorrect, but just incomplete (also in many other points).

Making a documentation out of sources can be ok, but then it must be
complete.
