Thread: clarify Regular Expression Functions in 9.7.3. POSIX RegularExpressions

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/10/static/functions-matching.html
Description:

Example: 

(as a heading) regexp_replace 
The regexp_replace function provides ... patterns.

Syntax:  regexp_replace(source, pattern, replacement [, flags ]). 

Operation: The source string ... replacement text. 

Flags: optional text ... behavior. 

Flag g specifies ...

Other flags are described in Table 9.22.

I see no need to explicitly specify flag i, as it is in the Table.
